NAME

   tin, rtin - Usenet newsreader

SYNOPSIS

   tin  [[-h|-H|-V] |  [[[-a]  [-dlnq|-Q]  [-ArzxX]] [[-R|-S] -s News_dir]
   [-cuvZ]  [-4|-6]  [-N|-M  address]  [-o|-w]]   [-D   debug_level]   [-G
   article_limit] [-f newsrc_file] [-g server] [-m Mail_dir] [-p port] [-I
   index_dir] [newsgroup[,...]]]

DESCRIPTION

   tin is a full-screen easy to use Usenet newsreader. It  can  read  news
   locally (e.g., /var/spool/news) or remotely (rtin or tin -r option) via
   a NNTP (Network News Transport Protocol) server. It will  automatically
   utilize  NOV  newsoverview(5) style index files if available locally or
   via the NNTP [X]OVER command (RFC2980, RFC3977).

   tin has four separate  levels  of  operation:  Selection  level,  Group
   level,  Thread  level  and Article level. Use the Help ('h') command to
   view a list of the commands available at a particular level.

   On  startup  tin  will  show  a  list  of  the  newsgroups   found   in
   ${TIN_HOMEDIR:-"$HOME"}/.newsrc.  An arrow '->' or highlighted bar will
   point to the first newsgroup. Move to a group  by  using  the  terminal
   arrow  keys  (terminal  dependent)  or  Down  ('j')  and  Up ('k'). Use
   PgUp/PgDn (terminal dependent) or PageUp ('^U') (CTRL-U)  and  PageDown
   ('^D') (CTRL-D) to page up/down. Enter a newsgroup by pressing '<CR>'.

   The  GroupNextUnreadArtOrGrp  ('<TAB>')  key  enters the next newsgroup
   with unread articles.

OPTIONS

   -4          Force connecting via IPv4 to the remote NNTP  server.  Only
               available when build with IPv6 support.

   -6          Force  connecting  via IPv6 to the remote NNTP server. Only
               available when build with IPv6 support.

   -a          Toggle ANSI color (default is off).

   -A          Force authentication on  initial  connect.  Only  available
               when reading via NNTP.

   -c          Create/update    index    files    for   every   group   in
               ${TIN_HOMEDIR:-"$HOME"}/.newsrc or file  specified  by  the
               ''-f'' option and mark all articles as read.

   -d          Don't  load  newsgroup  descriptions and servers message of
               the day (interactive mode).

   -D debug-level
               Enter debug-level (1 = NNTP, 2 = filter, 4 =  newsrc,  8  =
               threading,  16  = memory, 32 = attributes, 64 = misc, 128 =
               remove existing debug files).

   -f file     Use the specified file of subscribed to newsgroups in place
               of ${TIN_HOMEDIR:-"$HOME"}/.newsrc.

   -g server   Use     the     server     and    newsrc    specified    in
               ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable.  Only   available
               when reading via NNTP.

   -G article-limit
               Limit  the  number  of  articles/group to retrieve from the
               server.

   -h          Help listing all command-line options.

   -H          Brief introduction to tin that is also shown the first time
               it is started.

   -I dir      Directory  in which to store newsgroup index files. Default
               is
               ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news.
               This option has no effect if tin retrieves its index  files
               via NNTP and cache_overview_files is turned off.

   -l          Get    number    of    articles    per   group   from   the
               ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file.
               If  reading  via  NNTP  this  is done with the LIST command
               (RFC3977 ). This might result in incorrect  article  counts
               but is usually faster than the default which is to read the
               ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file
               (either  directly  or  via LIST) and then check the article
               count via NNTP GROUP command (RFC3977 ) ''-ln''. If reading
               via  NNTP  and  LIST COUNTS (RFC6048 ) is available that is
               used instead as it gives more accurate article counts.

   -m dir      Mailbox     directory     to      use.      Default      is
               ${TIN_HOMEDIR:-"$HOME"}/Mail.

   -M user     Mail  unread  articles to specified user for later reading.
               For more information read section  "AUTOMATIC  MAILING  AND
               SAVING NEW NEWS".

   -n          Only          load          groups         from         the
               ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file
               that     are     subscribed     to     in     the    user's
               ${TIN_HOMEDIR:-"$HOME"}/.newsrc. This allows  a  noticeable
               speedup when connecting via a slow line, but tin may not be
               able detect which groups are moderated. See also ''-l''.

   -N          Mail unread articles to yourself  for  later  reading.  For
               more information read section "AUTOMATIC MAILING AND SAVING
               NEW NEWS".

   -o          Quick post all postponed articles and exit.  In  order  for
               this  to  be really quick, it should be used with ''-n'' if
               possible.

   -p port     Port to use if reading via NNTP (default is 119). This also
               overrides  the  environment variable $NNTPPORT if set. Only
               available when reading via NNTP.

   -q          Don't check for new newsgroups and skip loading the servers
               message of the day.

   -Q          Quick  start.  Start  tin as quickly as possible. Currently
               this is equivalent to ''-nqd''.

   -r          Read news remotely from the default NNTP  server  specified
               in the environment variable $NNTPSERVER or contained in the
               file /etc/news/server.

   -R          Read news saved by the ''-S'' option.

   -s dir      Save/read   articles   to/in    directory.    Default    is
               ${TIN_HOMEDIR:-"$HOME"}/News.

   -S          Save  unread  articles  for  later  reading  by  the ''-R''
               option.  For  more  information  read  section   "AUTOMATIC
               MAILING AND SAVING NEW NEWS".

   -u          Create/update    index    files    for   every   group   in
               ${TIN_HOMEDIR:-"$HOME"}/.newsrc or file  specified  by  the
               ''-f'' option. This option is disabled if tin retrieves its
               index files via a NNTP server and  cache_overview_files  is
               turned off.

   -v          Verbose mode for ''-c'', ''-M'', ''-N'', ''-S'', ''-u'' and
               ''-Z'' options.

   -V          Print version and date information.

   -w          Quick mode to post an article and then exit. In  order  for
               this  to  be really quick, it should be used with ''-n'' if
               possible.

   -x          No-posting mode. You cannot post articles if you  use  this
               option.

   -X          No   overwrite  mode.  ${TIN_HOMEDIR:-"$HOME"}/.newsrc  and
               files   in   ${TIN_HOMEDIR:-"$HOME"}/.tin   will   not   be
               overwritten but may be created if they don't exist.

   -z          Only start tin if there is any new/unread news. If there is
               news tin will position cursor at first  group  with  unread
               news. Useful for putting in login file.

   -Z          Check  if  there  is  any  new/unread  news  and  exit with
               appropriate status.  If  ''-v''  option  is  specified  the
               number of unread articles in each group is printed. An exit
               code 0 indicates no news, 1 that an error  occurred  and  2
               that new/unread news exists. Useful for writing scripts.

   tin  can  also  dynamically  change its options by the OptionMenu ('M')
   command. Any changes are written to ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.
   For  more  information  see  section  "GLOBAL  OPTIONS  MENU  AND TINRC
   CONFIGURABLE VARIABLES" and tin(5).

   A list of groups can be specified after the other command-line options.
   This can be useful if you wish to yank in or subscribe to a hand-picked
   subset of the active newsgroups. See the  section  "NEWSGROUP  LISTS  &
   WILDCARDS" for the types of pattern that tin understands.

   If you specify a single group-name, or a wildcard that matches a single
   group, then you will automatically  enter  that  group.  Otherwise  the
   normal  group  selection  screen will appear, but with all the matching
   groups present too, as though you had yanked just those groups in.

   With the ''-w'' flag a given group-name is used  as  default  group  to
   post  to.  If  more  than one group or a wildcard is specified only the
   first group respectively the first group that matches is used.

   Once you use SelectYankActive ('y') to yank in all  active  groups,  or
   SelectToggleReadDisplay  ('r')  to  toggle the read/unread status, then
   the command-line groups will be gone. You can use  SelectSyncWithActive
   ('Y')                   to                  reread                  the
   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file and get them
   back.

   NB:   With   the   ''-n''   flag,   only  unsubscribed  groups  in  the
   ${TIN_HOMEDIR:-"$HOME"}/.newsrc file (or the newsrc-file given  by  the
   ''-f''           command-line           switch          or          via
   ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable) can be matched.

   Command-line options have higher priority  than  attributes  and  tinrc
   options.   Thus,  command-line  option takes precedence over configured
   values.

USAGE

   NEWS ADMINISTRATION
   Maintaining Netnews on large networks of machines can be a pretty  time
   consuming  job  as I discovered when I was given the job of maintaining
   our news system and news users.

   A user starting tin for the first time can be automatically  subscribed
   to  a  list  of  newsgroups  that  are  deemed  appropriate by the news
   administrator. The subscriptions file should be created  in  your  news
   lib   directory   (i.e.,  ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions)  and
   should have file permissions set to 0644. If you read  news  via  NNTP,
   then  your  news server must support the LIST SUBSCRIPTIONS command. It
   is part of the NNTP List Extensions (RFC6048 ) and all  modern  servers
   should understand it.

   SCREEN FORMAT
   tin  has  four  separate  levels  of  operation: Selection level, Group
   level, Thread level and Article level.

   At the Selection level the title displays (the name of the news  server
   and)  the number of subscribed groups (containing new unread articles).
   The newsgroups are displayed in the middle of the screen  usually  with
   the  number of unread articles displayed on the same line in front, but
   it can be customized via select_format.

   There may also be  a  character  prefixing  the  line.  An  explanation
   follows:

   u         This  group  is  unsubscribed.  To  see  only your subscribed
             groups   use    the    SelectToggleReadDisplay    ('r')    or
             SelectYankActive ('y') toggle keys.

   M         This is a moderated group. Any posts you make will have to be
             approved by the group administrator before it  will  be  made
             public.  tin  will  ask for confirmation before you post to a
             moderated group.

   N         This is a new newsgroup which has been created since you last
             used  tin.  New  newsgroups  are not subscribed to by default
             (However,   see   the   $AUTOSUBSCRIBE   /   $AUTOUNSUBSCRIBE
             environment variables).  Subscribe to it in the normal way if
             you wish the group to continue to appear  in  your  Selection
             Menu.  Simply ignore new newsgroups and they will be gone the
             next time you start tin. You will have to  yank  in  all  the
             groups to find them in a later session.

   D         This  group  no  longer  exists. If you no longer wish to see
             this group then unsubscribe from it in the normal  way.  This
             flag will only appear if you have set strip_bogus to "ask" in
             the Options Menu.

   X         You may no longer make posts to this  group.  Often  a  group
             will be superseded by a more appropriately named one.

   =         This group has been renamed and you may no longer post to it.
             If you do, then you will receive  an  error  from  your  news
             server telling you the correct group to post to.

   At the Group level the title contains the name of the group, the number
   of   conversation   threads,   the   abbreviated    threading    method
   (thread_articles), the limit of articles to get (if set; getart_limit),
   the   total   number   of   (unread)   articles   (art_marked_read   or
   art_marked_unread), the number of hot articles art_marked_selected, the
   number of read hot articles  (if  any;  art_marked_read_selected),  the
   number  of recent articles (art_marked_recent) and the number of killed
   articles (art_marked_killed). I.e.:

               alt.sources (5B -50/23+ 0* 3o 0K)

   The characters after the numbers are depending to the configuration and
   if your are in show_only_unread_arts mode or not. Some numbers could be
   missing if the specific option is not enabled. It might also contain an
   'M',  'X'  or '=' (see above; doesn't work with the ''-n'' command-line
   switch!) if the group is moderated, set to no posting or postings to it
   get redirected.

   If  a thread has unread articles it is marked with art_marked_unread in
   front of the total number of articles  in  the  thread.  If  there  are
   recent   articles   within   the   thread   it  might  be  marked  with
   art_marked_recent in front of the  total  number  of  articles  in  the
   thread  - this is controlled by the recent_time option. If a thread has
   hot articles in it (see also section "FILTERING ARTICLES") it's  marked
   with  art_marked_selected  in  front of the total number of articles in
   the thread. The number of lines of the first (unread)  article  in  the
   thread  might  also  be  shown  right  before  the  subject  -  this is
   controlled by the show_info option. The display can be  customized  via
   group_format.

   COMMON MOVING KEYS
   This  table  shows  the  common  keys used for moving around all levels
   within tin.

          Line Down             Down arrow   Down (j or ^N)

   COMMON EDITING COMMANDS
   An emacs(1) style editing package allows  the  easy  editing  of  input
   strings.   A  history  list allows the easy reuse of previously entered
   strings.  In addition to the cursor keys, the  following  commands  are
   available when editing a string:

   ^A, ^E    move to beginning or end of line, respectively.

   ^F, ^B    non-destructive   move   forward   or   back   one  location,
             respectively.

   ^D        delete the character currently under the cursor, or send  EOF
             if no characters in the buffer.

   ^H, <DEL> delete character left of the cursor.

   ^K        delete from cursor to end of line.

   ^P, ^N    move through history, previous and next, respectively.

   ^L, ^R    redraw the current line.

   <CR>      places line on history list if non-blank, appends newline and
             returns to the caller.

   <ESC>     aborts the present editing operation.

   GLOBAL COMMANDS
   The following commands are available at all 4 menu  levels  and  always
   have the same effect.

   ShellEscape '!'
             Shell  escape.  ShellEscape  by  itself  will launch a shell,
             ShellEscape <command> will run an  external  <command>.  This
             facility may have been disabled by the System Administrator.

   ToggleColor '&'
             Toggle use of ANSI color.

   RedrawScr '^L'
             Redraw the current screen.

   ScrollUp '<'
             Scroll screen up by one line.

   ScrollDown '>'
             Scroll screen down by one line.

   Postponed 'O' '^O'
             Reload postponed article. If your system blocks the Postponed
             key you must quote it by pressing '^V'  (CTRL-V)  first.  The
             postpone-menu offers the following actions: PromptYes ('y') =
             reload  and  spawn  editor;  PostponeOverride  ('Y')  =  post
             article  (without  spawning editor); PostponeAll ('A') = post
             all postponed articles (without  spawning  editor);  PromptNo
             ('n')  = skip this article; Quit ('q') = quit postponed menu.
             Currently there is no 'simple'  way  to  delete  a  postponed
             article   from  the  postponed-file,  you  have  to  use  the
             following command sequence instead: reload it with Postponed,
             enter  editor  with  PromptYes,  quit editor, discard posting
             with Quit ('^O''y''q'). See also ''-o'' command-line switch.

   Help 'h'  Help screen of commands available on the  current  menu.  You
             can use SearchSubjF ('/'), SearchSubjB ('?') and SearchRepeat
             ('\') to search on this screen. Quit  ('q')  returns  to  the
             menu.

   ToggleHelpDisplay 'H'
             Toggle  the  display  of  help mini menu at the bottom of the
             screen.

   GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES
   At startup, tin reads in the configuration  files  (see  also  tin(5)).
   They  contain a list of variables that can be used to configure the way
   tin works. If it exists, the global configuration file,  /etc/tin/tinrc
   is  read.  After  that,  the user's own configuration file is read from
   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.  The  global  file  is  useful  for
   distributing  system-wide  defaults  to  new  users who have no private
   tinrc yet.

   The     variables     are     user     configurable     by      editing
   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc  directly.  Most of them can also be
   set in the GLOBAL OPTIONS MENU which is accessed by pressing OptionMenu
   ('M')  at  all  levels. It allows the user to customize the behavior of
   tin.     The     options      are      saved      to      the      file
   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc  when you exit tin so don't edit the
   file directly whilst tin is running.

   In the options menu use the cursor  keys  in  the  usual  way  to  move
   around. Use ConfigSelect ('^J' or '<CR>') to 'open' the option you wish
   to change. You will need to enter a  new  value  or  use  '<SPACE>'  to
   toggle  the  available  options.  ConfigSelect will save the new value,
   '<ESC>' will abort without saving changes.

   As with the other menus, RedrawScr ('^L') will redraw the  screen.  You
   can  use SearchSubjF ('/'), SearchSubjB ('?') and SearchRepeat ('\') to
   search for a specific option. Use Quit ('q') to exit  the  option  menu
   and  keep  your changes. Use QuitTin ('Q') to exit without keeping your
   changes.

   The options menu provides access to the attributes menu for the current
   group   by   the   ConfigToggleAttrib   ('<TAB>')   command.   Pressing
   ConfigToggleAttrib again toggles back to the  options  menu.  For  more
   information see section "ATTRIBUTES MENU AND GROUP ATTRIBUTES".

   The  ConfigScopeMenu  ('S') command brings up the scopes menu. For more
   information see section "SCOPES MENU".

   Here is a full list of all the available variables. The name in  braces
   is     the     name     of     the     corresponding     setting     in
   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.

       OFF.

   Regex used to show external quotes (extquote_regex)
       A regular expression that will be applied  when  reading  articles.

       Specifies whether a screen  redraw  should  always  be  done  after
       certain external commands. Default is OFF.

   Number of articles to get (getart_limit)
       If  getart_limit  is  >  0  not  more  than  the  last getart_limit
       articles/group are fetched from the server. If getart_limit is <  0
       tin  will  start  fetching  articles  from  your first unread minus
       absolute value of getart_limit. Default is 0, which means no limit.

   Catchup group using left key (group_catchup_on_exit)
       If ON catchup group when leaving with the left arrow  key.  Default
       is ON.

   Format string for the Group level (group_format)

       section   "CUSTOMIZING   THE    SCREEN    FORMAT".    Default    is
       "%n %m %R %L  %s  %F".

   Go to the next unread article with (goto_next_unread)
       Which  keys  tin  should accept to jump to the next unread article.
       Possible is any combination of PageDown and  PageNextUnread.   When
       PageDown  is  set  tin  jumps to the next article at the end of the
       current one. When PageNextUnread is set tin  jumps  immediately  to
       the  next article when PageNextUnread ('<TAB>') is pressed. Default
       is PageNextUnread.

   Display uue data as an attachment (hide_uue)
       If set to 'No' then raw uuencoded data  is  displayed.  If  set  to
       'Yes'  then  sections of uuencoded data will be shown with a single
       tag line showing the size and filename (much the  same  as  a  MIME
       attachment).   If  set  to 'Hide all' then any line that looks like
       uuencoded data will be folded into a tag line. This is useful  when
       uuencoded  data  is split across more than one article but can also
       lead to false positives. This setting can also be  toggled  in  the
       article viewer.  Default is 'No'.

   External inews (inews_prog)
       Path,  name  and  options of external inews(1).  If you are reading
       via NNTP the default  value  is  "--internal"  (use  built-in  NNTP
       inews),  else it is "inews -h". The article is passed to inews_prog
       on STDIN via '< article'.

   (info_in_last_line)
       If ON, show current group description or  article  subject  in  the
       last  line  (not in the pager and global menu) - ToggleInfoLastLine
       ('i') toggles setting. This facility is useful as the full width of
       the screen is available to display long subjects. Default is OFF.

   Use interactive mail reader (interactive_mailer)
       Interactive  mailreader:  if greater than 0 your mailreader will be
       invoked earlier for reply so you can use more of its features (e.g.
       MIME,  pgp,  ...).  1  means include headers, 2 means don't include
       headers (old use_mailreader_i=ON option). 0 turns off  usage.  This
       option has to suit mailer_format. Default is 0.

   Use inverse video for page headers (inverse_okay)
       If  ON  use  inverse  video  for page headers and URL highlighting.
       Default is ON.

   Keep failed arts in ~/dead.articles (keep_dead_articles)
       If      ON      keep       all       failed       postings       in
       ${TIN_HOMEDIR:-"$HOME"}/dead.articles   besides  keeping  the  last
       failed posting in ${TIN_HOMEDIR:-"$HOME"}/dead.article. Default  is
       ON.

   Filter which articles (kill_level)
       This  option  controls  the processing and display of articles that
       are killed.  There are 3 options:

        0  Kill only unread arts is the  'traditional'  behavior  of  tin.
           Only unread articles are killed once only by marking them read.
           As filtering only happens on unread  articles  with  kill_level
           set  to  0,  art_marked_killed and art_marked_read_selected are
           only shown once. When you reenter the group the  mark  will  be
           gone.

        1  Kill  all  arts  & show with K will process all articles in the
           group and therefore there is a processing overhead  when  using
           this  option.  Killed  articles are threaded as normal but they
           will be marked with art_marked_killed.

        2  Kill all arts and never show will process all articles  in  the
           group  and  therefore there is a processing overhead when using
           this option. Killed articles simply does not get  displayed  at
           all.
   Default is 0 (Kill only unread arts).

   Use 8bit characters in mail headers (mail_8bit_header)
       Allows  8bit  characters  unencoded  in the header of mail message.
       Default  is   OFF.   Turning   it   ON   is   effective   only   if
       mail_mime_encoding  is also set to 8bit. Leaving it OFF is safe for
       most users and compliant to Internet  Mail  Standard  (RFC5322  and
       RFC2047). Default is OFF.

   Mail address (mail_address)
       User's  mail address (and full name), if not username@host. This is
       used when creating articles, sending mail and when pgp(1) signing.

   MIME encoding in mail messages (mail_mime_encoding)
       MIME encoding of the body in  mail  message,  if  necessary  (8bit,
       base64, quoted-printable, 7bit). Default is quoted-printable.

       %M=Message-ID,  %N=Fullname, %C=Firstname, %I=Initials). Default is
       "In article %M you wrote:"

   Format of the mailbox (mailbox_format)
       Select one of the following mailbox-formats: MBOXO (default, except
       on  SCO),  MBOXRD or MMDF (default on SCO). See mbox(5) and RFC4155
       for more details on MBOXO and MBOXRD and mmdf(5) for  more  details
       about MMDF.

   Mail directory (maildir)
       The  directory  where  articles/threads  are to be saved in mbox(5)
       format. This feature  is  mainly  for  use  with  the  elm(1)  mail
       program.  It allows the user to save articles/threads/groups simply
       by  giving  '='  as  the  filename  to   save   to.    Default   is
       ${TIN_HOMEDIR:-"$HOME"}/Mail.

   Invocation of your mail command (mailer_format)
       The format string used to create the mailer command with parameters
       that is used for mailing articles to other people. Default  is  '%M
       "%T" < %F' (e.g., /bin/mail "iain" < .article). The flexible format
       allows other mailers with different command line parameters  to  be
       used such as
          sendmail -oem -t < %F
          elm -s "%S" "%T" < "%F"
          claws-mail --compose "mailto:%T?subject=%S&insert=%F"
       interactive_mailer    must   be   set   adequate.   The   following
       substitutions are supported:
          %F              filename
          %M              default_mailer
          %S              subject-field
          %T              to-filed
          %U              username
          %%              %

   'Mark as (un)read' ignores tags (mark_ignore_tags)
       When this is  ON,  the  GroupMarkThdRead  ('K'),  ThreadMarkArtRead
       ('K'),  MarkThdUnread  ('Z') at Group level and MarkArtUnread ('z')
       at Thread level functions mark just the current article or  thread,
       ignoring  other  tagged,  (un)read  articles.  When  OFF,  the same
       function presents a menu with choices  of  the  current  thread  or
       article, all tagged, unread articles, or nothing.

   Mark saved articles/threads as read (mark_saved_read)
       If ON mark articles that are saved as read. Default is ON.

   Viewer program for MIME articles (metamail_prog)
       Path, name and options of external metamail(1) program used to view
       non-textual parts of articles.  To use the built-in viewer, set  to
       --internal.  This  is  the  default  value  when metamail(1) is not
       installed. Leave it blank if you don't want any  automatic  viewing
       of  non-textual  attachments. The 'V' command can always be used to
       manually view any attachments. See also ask_for_metamail.

   MM_CHARSET (mm_charset)
       Charset supported locally, which  is  also  used  for  MIME  header
       (charset parameter and charset name in header encoding) in mail and
       news postings. If MIME_STRICT_CHARSET is defined at  compile  time,
       text  in  charset  other  than  the  value  of  this  parameter  is
       considered not displayable and represented as '?'.  Otherwise,  all
       character sets are regarded as compatible with the display. If it's
       not set, the value of the environment variable $MM_CHARSET is used.
       US-ASCII or compile-time default is used in case neither of them is
       defined. If your system supports iconv(3), this option is  disabled
       and you should use mm_network_charset instead.

   MM_NETWORK_CHARSET (mm_network_charset)
       Charset  used  for  posting  and MIME headers; replaces mm_charset.
       Conversion between mm_network_charset and local charset (determined
       via  nl_langinfo(3))  is done via iconv(3), if this function is not
       available on your system this option is disabled and  you  have  to
       use mm_charset instead. mm_network_charset is limited to one of the
       following charsets:
          US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU}
          EUC-{CN,JP,KR,TW},    ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2},   Big5,
          UTF-8
       Not all values might work on your  system,  see  iconv_open(3)  for
       more  details.  If  it's  not  set,  the  value  of the environment
       variable $MM_CHARSET is used. US-ASCII or compile-time  default  is
       used in case neither of them is defined.

   Attribute of highlighting with _dash_ (mono_markdash)
       Character  attribute of words emphasized like _this_. It depends on
       your   terminal   which   attributes   are   usable.    See    also
       word_h_display_marks and word_highlight.

   Attribute of highlighting with /slash/ (mono_markslash)
       Character  attribute of words emphasized like /this/. It depends on
       your   terminal   which   attributes   are   usable.    See    also
       word_h_display_marks and word_highlight.

   Attribute of highlighting with *stars* (mono_markstar)
       Character  attribute of words emphasized like *this*. It depends on
       your   terminal   which   attributes   are   usable.    See    also
       word_h_display_marks and word_highlight.

   Attribute of highlighting with -stroke- (mono_markstroke)
       Character  attribute of words emphasized like -this-. It depends on
       your   terminal   which   attributes   are   usable.    See    also
       word_h_display_marks and word_highlight.

   (newnews)
       These  are  internal  timers  used  by  tin  to  keep  track of new
       newsgroups.  Do not change them unless you understand what they are
       for.

   Display these header fields (or *) (news_headers_to_display)
       Which  news  headers  you wish to see. If you want to see _all_ the
       headers, place an '*' as  this  value.  This  is  the  only  way  a
       wildcard can be used.  If you enter 'X-' as the value, you will see
       all headers beginning with 'X-' (like X-Alan or  X-Pape).  You  can
       list more than one by delimiting with spaces. Not defining anything
       turns off this option.

   Do not display these header fields (news_headers_to_not_display)
       Same as news_headers_to_display except it denotes the opposite.  An
       example  of using both options might be if you thought 'X-' headers
       were A Good Thing(tm), but thought Alan and Pape were miscreants...
       well     then     you     would    do    something    like    this:
       news_headers_to_display=X-       news_headers_to_not_display=X-Alan
       X-Pape Not defining anything turns off this option.

   Quote line when following up (news_quote_format)
       Format   of   quote  line  when  posting/following  up  an  article
       (%A=Address,    %D=Date,     %F=Fullname+Address,     %G=Groupname,
       %M=Message-ID,  %N=Fullname, %C=Firstname, %I=Initials). Default is
       "%F wrote:".

   NNTP read timeout in seconds (nntp_read_timeout_secs)
       Time in seconds to wait for a response from the server. Default  is
       120.  Setting this to 0 means no timeout.

       if  set this also disables the generation of MIME-headers when they
       are  usually  required.   Default   is   OFF.   Only   enacted   if
       post_mime_encoding  is  also  set  to  8bit.  In  a number of local
       hierarchies where 8bit characters are used, using  unencoded  (raw)
       8bit   characters  in  header  is  acceptable  and  sometimes  even
       recommended so that you need to check the convention adopted in the
       local  hierarchy of your interest to determine what to do with this
       and post_mime_encoding.

   MIME encoding in news messages (post_mime_encoding)
       MIME encoding of the body in news  message,  if  necessary.  (8bit,
       base64, quoted-printable, 7bit). Default is 8bit, which leads to no
       encoding.  base64 and quoted-printable  are  usually  undesired  on
       usenet.

   View post-processed files (post_process_view)

       be  turned  into  '>>>'). The default is to compress quotes, and to
       quote empty lines.
       When you are viewing an article in raw mode ('^H'), and  follow  up
       or  reply  to  it,  the  signature  will be quoted even if it would

       matched using the wildmat notation.

   What to display instead of mark (word_h_display_marks)

       used  for word highlighting else the character attributes specified
       in mono_markdash, mono_markslash, mono_markstar and mono_markstroke
       are used. Default is ON.

   Page line wrap column (wrap_column)
       Sets  the  column  at  which  a  displayed  article  body should be

       screen  width.   If  this value is greater than your current screen
       width the part off-screen  is  not  displayed.  Thus  setting  this
       option  to  a  large value can be used to disable wrapping. If this
       value is negative the wrap margin is the current screen width  plus
       the given value (as long as the result is still positive, otherwise
       it will fall back to the  current  screen  width).  Default  is  0,
       wrapping at the current screen width.

       Format  is  the  same  as  for news_quote_format, this is used when
       answering  to  a   crossposting   to   several   groups   with   no
       ''Followup-To:'' set.

   ATTRIBUTES MENU AND GROUP ATTRIBUTES
   tin  allows  certain  attributes  to be set on a per group basis. If it
   exists,          the          global          attributes          file,
   ${TIN_LIBDIR:-NEWSLIBDIR}/attributes  is  read.  After that, the user's
   own attributes file  ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes  is  read.
   The  global  attributes  file  is  useful  for distributing system-wide
   defaults to new users who have no private attributes file yet.

   Note that the scope=<grouplist> line has to  be  specified  before  the
   attributes  are  specified  for  that list. All attributes are set to a
   reasonable default so you only have to specify the attribute  that  you
   want  to  change  (e.g.,  savedir).  All  toggle  attributes are set by
   specifying ON/OFF. Otherwise, these function exactly the same as  their
   global equivalents. For more details see tin(5).

   Attributes  can  also  be changed from the attributes menu which can be
   accessed by ConfigToggleAttrib  ('<TAB>')  from  the  options  menu  or
   ScopeSelect ('^J' or '<CR>') from the scopes menu.  The attributes menu
   looks and behaves very similar to the options menu. The title shows the
   current  scope. Attributes set in the current scope are marked with '+'
   to the left of the attributes number.

   Besides the keys for moving around and changing values known  from  the
   options  menu  the  attributes  menu  provides  the  following command:
   ConfigResetAttrib ('r') which resets an attribute to a default value.

   SCOPES MENU
   The scopes menu (accessible from the options menu with  ConfigScopeMenu
   ('S')) shows all scopes read from the global and local attributes file.
   Scopes from the global attributes file are marked with '!' to the  left
   of  the  scope  number.  Delete/rename/move are not possible with those
   scopes.

   In addition to the  common  moving  keys  the  following  commands  are
   available:  ScopeSelect  ('^J' or '<CR>') enter the attributes menu for
   the  current  scope,  ScopeEditAttributesFile  ('E')  edit  the   local
   attributes  file,  ScopeAdd  ('a')  add  a new scope, ScopeDelete ('d')
   delete the current scope, ScopeMove ('m') move the current scope  to  a
   new   position,   ScopeRename   ('r')   rename   the   current   scope.
   ToggleHelpDisplay ('H') toggles the help mini menu at the bottom of the
   screen.

   FILTERING ARTICLES
   When  there  is  a  subject  or  an  author  which  you are either very
   interested  in,  or  find  completely  uninteresting,  you  can  easily
   instruct tin to auto-select or auto-kill articles that match rules that
   you specify. This can be anything from the name of the  author  to  the
   number of lines in an article.

   When       tin       starts      up      the      user's      kill-file
   ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (see also  tin(5))  is  read.  Each
   time  a  newsgroup is entered the rules are applied and articles killed
   or selected when they meet certain criteria.

   The degree to which rules are applied depend on  the  kill_level  tinrc
   setting.  By  default  killed articles will only be marked read. Adjust
   kill_level for more aggressive processing. Articles that match an auto-
   selection rule are marked with a ''*''.

   Filtering      rules      can      be     manually     entered     into
   ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (but don't do this  whilst  running
   tin  else  you  will  lose  your changes) or by using an on-screen menu
   within tin.

   The filtering capabilities of tin have been significantly enhanced over
   previous versions to include scoring and better pattern matching. It is
   recommended that you read the file filtering in the  tin  documentation
   directory. This file can also be read online at
   <http://www.tin.org/filtering.txt>.

   The  on-screen  filtering  menu  is accessed by pressing MenuFilterKill
   ('^K') or MenuFilterSelect ('^A') at the Group and Article  levels.  It
   allows  the  user to kill or select an article that matches the current
   ''Subject:'' line, ''From:'' line or a string entered by the user.  The
   user  entered  string  can  be applied to the ''Subject:'' or ''From:''
   line of an article. The filter can be limited to the current  newsgroup
   or  it can apply to all newsgroups. Once entered the user can abort the
   command and not save the new filter, edit the full filter file or  save
   filter.

   POSTING ARTICLES
   tin  allows  posting  of articles, follow-up to already posted articles
   and replying direct through mail to the author of an article.

   Use the Post ('w') command to post an article to  a  newsgroup.   After
   entering  the  post  subject  the  default  editor (i.e., vi(1)) or the
   editor specified by the $VISUAL or $EDITOR environment variable will be
   started  and  the  article can be entered. To crosspost articles simply
   add a comma and the  name  of  the  newsgroup(s)  to  the  end  of  the
   ''Newsgroups:''  line at the beginning of the article. After saving and
   exiting the editor you are asked if you  wish  to  a)bort  posting  the
   article,  e)dit the article again or p)ost the article to the specified
   newsgroup(s).

   Use the DisplayPostHist ('W') command  to  display  a  history  of  the
   articles  you  have  posted.  The  date  the  article was posted, which
   newsgroups the article was posted to and the articles subject line  are
   displayed.

   Use    the    PageFollowupQuote    ('f'),    PageFollowup    ('F')   or
   PageFollowupQuoteHeaders ('^W') command to post a follow-up article  to
   an  already posted article. The PageFollowupQuote command will copy the
   text   of   the    original    article    into    the    editor.    The
   PageFollowupQuoteHeaders  command will copy the text and all headers of
   the original article into the editor. The editing procedure is the same
   as when posting an article with the Post ('w') command.

   Use  the PageReplyQuote ('r'), PageReply ('R') or PageReplyQuoteHeaders
   ('^E') command to reply direct through mail to the author of an already
   posted  article.  The  PageReplyQuote command will copy the text of the
   original article into the  editor.  The  PageReplyQuoteHeaders  command
   will  copy  the  text  and all headers of the original article into the
   editor. The editing procedure is the same as when  posting  an  article
   with  the  Post  ('w') command. After saving and exiting the editor you
   are asked if you wish to abort sending the article via PostAbort ('a'),
   edit  the  article  again via PostEdit ('e') or send the article to the
   author via PostSend ('s').

   CUSTOMIZING THE ARTICLE QUOTE STRING
   When posting a followup to an article or replying direct to the  author
   of  an  article  via  email  the text of the article can be quoted. The
   beginning of the quoted text can contain information about  the  quoted
   article  (e.g.,  Name  and the Message-ID of the article). To allow for
   different situations certain information from the article can  be  used
   in  the quoted string. The following variables are expanded if found in
   the   tinrc   variables   mail_quote_format,    news_quote_format    or
   xpost_quote_format:
          %A  Address (Email)
          %D  Date (uses date_format)
          %F  Full address (%N <%A>)
          %G  Groupname
          %M  Message-ID
          %N  Fullname of author
          %C  Firstname of author
          %I  Initials of author
   e.g.,
          mail_quote_format=On %D in %G you wrote:
          news_quote_format=In %M, %F wrote:
   would expand to:

   The  quoted  text  section of an article is marked by a preceding quote
   string at the beginning of each quoted line. The default  quote  string
   is  set  to  '>_'.  The  default  can  be  changed by setting the tinrc
   variable quote_chars to ones own preference. (Note that  '_'  underline
   is used to represent a space).

   MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
   The  command  interface  to GroupMail, PageMail, PostMail or ThreadMail
   ('m'), Pipe ('|'), Print ('o'), PageRepost  or  GroupRepost  ('x')  and
   GroupSave,  PageSave or ThreadSave ('s' and GroupAutoSave, PageAutoSave
   or ThreadAutoSave 'S') articles is the same for ease of use.

   Auto-saving with *AutoSave ('S') is a special case and operates only on
   marked  articles.  They  will  processed  without any further prompting
   according to the default save parameters defined in  tinrc  or  by  any
   attributes set for the current group.

   Otherwise,  the  initial  prompt  will ask you to select which article,
   thread,  hot  (auto-selected),  regular  expression   pattern,   tagged
   articles you wish to mail, pipe etc.

   Tagged  articles  must  have  already  been  tagged  with  a *Tag ('t')
   command. All tagged articles can be untagged by a  *Untag  ('U')  untag
   command.

   If  a  regular  expression pattern is selected you are asked to enter a
   pattern (e.g., to match all  articles  subject  lines  containing  'net
   News'  you  enter  "net  News").  Any  articles  that match the entered
   expression will be mailed, piped  etc.  See  also  the  wildcard  tinrc
   variable for advanced pattern matching options.

   Various expansion characters are recognized when entering the directory
   and file to save to. Environment variables (prefixed with '$') and user
   home  directories  (prefixed  by  '~' or '~username') can be specified.
   Environment variables can themselves contain other special characters.

   To save articles to a mailbox enter '=<mailbox name>'  when  asked  for
   the save filename. If you enter just '=' then articles will be saved to
   a mailbox with the name of the  current  newsgroup  (eg,  alt.sources).
   See maildir.

   To    save   in   savedir/<news.group.name>/<filename>   format   enter
   '+<filename>'.  Environment variables are  allowed  within  a  filename
   (e.g., $SOURCES/dir/filename). See savedir.

   When  saving articles you can specify whether the saved files should be
   post   processed.   A   default   process   type   can   be   set   via
   post_process_type.

   AUTOMATIC MAILING AND SAVING NEW NEWS
   tin  allows  new/unread  news  articles to be mailed (''-M'' and ''-N''
   option) or saved (''-S'' option)  in  batch  mode  for  later  reading.
   Useful when going on holiday and you don't want to return and find that
   expire has removed a whole load of unread articles.  Best  to  run  via
   cron(1) everyday while away, after which you will be mailed a report of
   which articles were mailed/saved from which newsgroups  and  the  total
   number  of  articles mailed/saved. Articles are saved in a private news
   structure    under    your    savedir     directory     (default     is
   ${TIN_HOMEDIR:-"$HOME"}/News).   Be careful of using this option if you
   read a lot of groups because you could overflow your file system.

   When using ''-S'' together with a given directory to  save  to  (''-s''
   option), the same directory must be specified when reading the articles
   by ''-R''.

   If you only want to save some of your groups use the  batch_save  tinrc
   variable.  Set  to  ON  or OFF in tinrc to enable/disable saving of all
   groups and then use the batch_save attribute to fine tune which  groups
   you  want  to have saved. For example, if you want to save most of your
   groups, then set batch_save to ON in tinrc and selectively turn off the
   ones you don't want using attributes.

   tin -M iain -c -f newsrc.mail
                       (mail  any  unread articles in newsgroups specified
                       in file newsrc.mail to the local user iain and mark
                       them as read)

   tin -S -c -f newsrc.save
                       (save  any  unread articles in newsgroups specified
                       in file newsrc.save and mark them as read)

   tin -R              (read any articles saved by tin -S)

   RANGES
   A range is simply a group of items marked using the SetRange ('#') key.
   Certain  tin commands will operate on a range if one exists rather than
   just  the  current  item.  A  range  is  an  expression  of  the   form
   <min>-<max>,  e.g.  10-15  will  highlight  items  10 through 15 on the
   current screen. Other than absolute numeric positions, '.' can be  used
   in place of the current cursor position and '$' can be used to mean the
   highest number available. Currently the only commands  that  understand
   ranges    are   GroupMarkThdRead   ('K'),   MarkArtUnread   ('z')   and
   MarkThdUnread ('Z').

   NEWSGROUP LISTS & WILDCARDS
   Several places in tin allow you to specify a list of newsgroups.  These
   include     command-line     groups,    (un)subscribe    groups,    the
   AUTO[UN]SUBSCRIBE mechanism. The scope= attributes  file  tag  and  the
   filter  file  group=  tag also use the same syntax. tin interprets this
   variable similarly to rn(1).  It contains a list of patterns, separated
   by commas and possibly prefixed with exclamation points. An exclamation
   point negates the meaning of a match on this pattern, and can  be  used
   to cancel certain matches. Some examples:

   alt.config,news.*,!news.test

   Matches  alt.config  and  everything  in  the  'news'  hierarchy except
   news.test

   See the  explanation  for  the  $AUTOSUBSCRIBE  variables  for  further
   examples.

   SIGNATURES
   tin       will      recognize      a      signature      in      either
   ${TIN_HOMEDIR:-"$HOME"}/.signature or ${TIN_HOMEDIR:-"$HOME"}/.Sig.  If
   ${TIN_HOMEDIR:-"$HOME"}/.signature  exists,  then the signature will be
   pulled  into  the  editor  for  mail  commands  only.  A  signature  in
   ${TIN_HOMEDIR:-"$HOME"}/.signature  will  not be pulled into the editor
   for posting commands since inews(1) will append the signature itself.

   A signature in ${TIN_HOMEDIR:-"$HOME"}/.Sig will  be  pulled  into  the
   editor for both posting and mailing commands.

   The following is an example of a .Sig file:
          NAMES  Joe Bar <joe@example.org>
          SNAIL  Musterweg 12, 99999 Notreal, Germany

   tin  also  has  the  capability  to generate random signatures on a per
   newsgroup basis if so desired. The way to accomplish this is to specify
   the default signature or the group attribute sigfile as a directory. If
   for example  the  sigfile  path  is  /usr/iain/.sigs  and  .sigs  is  a
   directory then tin will select a random signature from any file that is
   in the directory .sigs (note:  one  signature  per  numbered  file).  A
   random  signature  can  also consist of a fixed part signature that can
   contain your name, address etc. followed by the random sig.  The  fixed
   part of the random sig is read from the file $HOME/.sigfixed.

   CUSTOMIZING THE SCREEN FORMAT
   The look of the Selection, Group and Thread level can be customized via
   format strings.  These  format  strings  define  the  content  and  the
   position  of  each element on the screen. Variables are used within the
   format strings as placeholders. The following variables are available:

      %D    date
      %F    from, name and/or address
      %G    newsgroup name
      %I    initials
      %L    line count
      %M    message-id
      %R    number of responses in thread
      %S    score
      %T    thread tree
      %U    unread count
      %d    newsgroup description
      %f    newsgroup flag
      %m    article marks
      %n    current group/thread/article number
      %s    subject
      %%    %

   Not all variables can be  used  in  each  level.  The  following  table
   provides an overview:

          select_format group_format thread_format
      %D                      X            X
      %F                      X            X
      %G        X
      %I                      X            X
      %L                      X            X
      %M                      X            X
      %R                      X
      %S                      X            X
      %T                                   X
      %U        X
      %d        X
      %f        X
      %m                      X            X
      %n        X             X            X
      %s                      X
      %%        X             X            X

   Defaults for the format strings:

      select_format: "%f %n %U  %G  %d"
      group_format:  "%n %m %R %L  %s  %F"
      thread_format: "%n %m  [%L]  %T  %F"

   show_description controls whether the newsgroup description is shown or
   not. The description can also be toggled with  SelectToggleDescriptions
   ('d').

   The   information   displayed   with  '%F'  depends  on  the  value  of
   show_author.  GroupToggleSubjDisplay   resp.    ThreadToggleSubjDisplay
   ('d') switches through all available options.

   For  date  representation  '%D'  uses  date_format.  It  is possible to
   specify a different date format in round brackets  (e.g.  '%(%d  %b  %y
   %H:%M)D'). See date_format for more details.

   The  length  of  each item (except '%%') can be defined with a positive
   number after the '%'. The following example displays the score  in  the
   thread level 10 characters wide: '%10S'.

   If  the  newsgroup  name  is  displayed  together  with  the  newsgroup
   description, the width of the newsgroup name can be  controlled  via  a
   optional  comma separated second value (e.g. '%60,20G'). It is valid to
   omit the first value (e.g. ('%,20G')). If no second value is given, tin
   uses a default value of 32.

   Some  variables  do  have a default width which may lead to truncation.
   Truncation for variables which contain only numbers happens by dividing
   the  value with a sufficient power of ten and adding a SI suffix to the
   result, that is the variable holds a value of 54321 and the  width  for
   the  variable  is  4 the result will be "54 k". If that's undesired you
   have to specify a  larger  width  manually,  e.g.  '%6n'.  Here  is  an
   overview of the defaults:

      Variable  width
      %I         3
      %L         4
      %M        10
      %R         3
      %S         6
      %U         5
      %n         4

   If  no length is given for '%D', the length is determined by the format
   string for the date and the date of the current day. If the date format
   string contains weekdays or months names it may happen that the date is
   longer than determined in the first pass. In this  case,  the  date  is
   truncated  before  display.  This  occurs,  for example, if the current
   month is May and the article to which the date is displayed was  posted
   in  December.  In  such  cases it might useful to determine the maximum
   length manually and specify the length in the format string.

   In case the format string contains '%G' and  '%d'  and  no  length  are
   given,  tin  determines the longest newsgroup name and uses this length
   for '%G'. The remaining space will used for '%d'.

   When the format string contains the specifier '%F' and '%s' resp.  '%T'
   and  no  length  are given, '%F' will use one third and '%s' resp. '%T'
   will use two third of the available space.

   In addition, a minimum screen  width  can  be  defined  for  each  item
   (except  '%%').  In this case, the item will only be displayed when the
   screen is wider than specified. This comes in handy to not  overload  a
   small  screen  but  have  maximum  information  on  a large screen. The
   minimum screen width has to be specified by a positive number  preceded
   by  an '>'. In the following example tin will display the score only if
   the screen is wider than 100 characters: '%>100S'.

   If both the length and the minimum screen width should be specified for
   an  item, the length must be the first parameter and the minimum screen
   width must be the second one. The following example displays the  score
   with  a  length  of  10 characters only if the screen is wider than 100
   characters: '%10>100S'.

   TIPS AND TRICKS
   tin can be pretty much be navigated by using the four cursor keys.  The
   left  arrow key goes up a level, the right arrow key goes down a level,
   the up arrow key goes up a line and the down  arrow  key  goes  down  a
   line.

   The  following  newsgroups  provide  useful information concerning news
   software:
       —news.software.readers (info. about news user agents tin,  rn,  nn,
        slrn etc.)
       —news.software.nntp (info. about NNTP)
       —news.answers   (Frequently   Asked   Questions  (FAQ)  about  many
        different themes)

   Many prompts within tin offer a  default  choice  that  the  cursor  is
   positioned  on.  By  pressing  '<CR>' the default value is taken.  Most
   prompts can be aborted by pressing '<ESC>'.

   When tin is run in a xterm(1x) it will  resize  itself  each  time  the
   xterm(1x) is resized.

   tin                   will                  reread                  the
   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}   file   at   set
   intervals (reread_active_file_secs) to show any newly arrived news.

   If  you  find large number of new newsgroups cluttering up your screen,
   pressing SelectToggleReadDisplay ('r') will make them go away.

   XTERM BUTTONS
   If the environment variable $TERM is  set  to  xterm(1x),  then  button
   pressing can be used to select groups and articles. In this discussion,
   the buttons are assumed to be assigned conventionally (i.e., Button1 is
   the left button).

   In general (i.e., for the group, thread and article menus),

   Button1 (left)
             enters  next  (lower)  level  if  you  click  on  an article,
             otherwise pages down.

   Button2 (center)
             returns to the previous (upper) level  if  you  click  on  an
             article, otherwise pages up.

   Button3 (right)
             positions  on  the  article line under mouse cursor, or pages
             down if you've clicked outside the list of articles.

   In the group selection menu, if the mouse is pointing at a group then:

   left button
             moves  to  and  selects  the  group  pointed  at,  just  like
             SelectReadGrp ('<CR>').

   center button
             quits the program, just like Quit ('q').

   right button
             moves to the group pointed at.

   In the article menu, if the mouse is pointing at an article (or thread)
   then:

   left button
             reads the article pointed  at,  just  like  GroupReadBasenote
             ('<CR>'), or the thread, just like GroupListThd ('l').

   center button
             exits  the  menu,  catching  up  on  the  group  if  you have
             group_catchup_on_exit set in your  configuration,  just  like
             Quit ('q').

   right button
             moves to the article (or thread) pointed at.

   In the thread menu, if the mouse is pointing at an article then:

   left button
             reads article pointed at, just like ThreadReadArt ('<CR>').

   center button
             exits  the  menu,  catching  up  on  the  thread  if you have
             thread_catchup_on_exit set in your configuration,  just  like
             Quit ('q').

   right button
             moves to the article pointed at.

   In  other menus and areas button pressing reverts back to usual cut and
   paste of xterm(1x), but after one click of any button.

   INDEX FILES
   If your news server supports NOV index files (see newsoverview(5), most
   modern  installations will) and you have a fast connection to your news
   server then this section can be ignored.

   If your news server doesn't support NOV index files or you have a  very
   slow  connection  to  your news server then tin can cache the index for
   each newsgroup if cache_overview_files is set to ON.   Note  that  this
   cache  can  use  up  large  amounts  of disk space if you read a lot of
   groups and/or high traffic groups.

   Each user creates/updates his/her own index files that  are  stored  in
   ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news/. If you are
   reading via NNTP then the news server name will be appended to keep the
   indexes  for  different  servers  separate.  If you are reading off the
   local spool and local overview files  already  exist  then  turning  on
   caching will have no effect. Likewise unless you see significant delays
   entering a group when reading via NNTP then  turning  on  caching  will
   have little or no effect.

   Entering a group the first time tends to be slow because the index file
   must be built from scratch. To alleviate  the  slowness  start  tin  to
   create  all  index files for the groups you subscribe to with tin -u -v
   and go for a coffee. Subsequent readings of a group will only  need  to
   do  incremental  updating  of the index file and will be much faster as
   only new articles will need to be cached.

   As indexing might take some time you may  want  to  run  tin  form  the
   system batcher cron(1) with the ''-u'' option:

          30 6 * * * /usr/local/bin/tin -u

   If  you  are  low  on  local disk space you should consider to manually
   purge cached data for groups you are not reading anymore with something
   like:

          find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
          -type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT

   TINRC  Define this variable if you want to specify command-line options
          that tin should be started with to save typing them each time it
          is  started.  The contents of the environment variable are added
          to the front of the command-line options  before  it  is  parsed
          therefore  allowing  an  option specified on the command-line to
          override the same option specified in the environment.

   TIN_HOMEDIR
          Define this variable if you do not want the  .tin  directory  in
          $HOME/.  E.g.,  if you want all tin's private files in /tmp/.tin
          you would set $TIN_HOMEDIR to /tmp.

   TIN_INDEX_NEWSDIR
          Define this variable if you do not want the .news  directory  in
          ${TIN_HOMEDIR:-"$HOME"}/.tin/.  E.g., if you want all tin's news
          index files in /tmp/.news you would  set  $TIN_INDEX_NEWSDIR  to
          /tmp.

   TIN_INDEX_MAILDIR
          Define  this  variable if you do not want the .mail directory in
          ${TIN_HOMEDIR:-"$HOME"}/.tin/. E.g., if you want all tin's  mail
          index  files  in  /tmp/.mail you would set $TIN_INDEX_MAILDIR to
          /tmp.

   TIN_INDEX_SAVEDIR
          Define this variable if you do not want the .save  directory  in
          ${TIN_HOMEDIR:-"$HOME"}/.tin/.  E.g., if you want all tin's save
          index files in /tmp/.save you would  set  $TIN_INDEX_SAVEDIR  to
          /tmp.

   TIN_LIBDIR
          Define this variable if you want to override the NEWSLIBDIR path
          that was compiled into the tin binary, default is /usr/lib/news.
          If  tin  is  running  in  NNTP mode setting this variable has no
          effect.

   TIN_SPOOLDIR
          Define this variable if you want to override the  SPOOLDIR  path
          that   was   compiled   into   the   tin   binary,   default  is
          /var/spool/news.  If tin is running in NNTP  mode  setting  this
          variable has no effect.

   TIN_NOVROOTDIR
          Define this variable if you want to override the NOVROOTDIR path
          that was compiled into the tin binary, default is SPOOLDIR  (see
          above). If tin is running in NNTP mode setting this variable has
          no effect.

   TIN_NOVFILENAME
          Define this variable if you want to override  the  OVERVIEW_FILE
          filename  that  was  compiled  into  the  tin binary, default is
          .overview. If tin is running in NNTP mode setting this  variable
          has no effect.

   TIN_ACTIVEFILE
          Define   this   variable   if   you   want   to   override   the
          NEWSLIBDIR/active path that was compiled into the tin binary. If
          tin is running in NNTP mode setting this variable has no effect.
          If $TIN_LIBDIR is set it is prepended to $TIN_ACTIVEFILE.

   NNTPSERVER
          The default  NNTP  server  to  remotely  read  news  from.  This
          variable  only needs to be set if the ''-r'' command-line option
          is specified and the file /etc/news/server does not  exist.  The
          ''-g'' command line option overrides $NNTPSERVER.

   NNTPPORT
          The NNTP TCP-port to read news from. This variable only needs to
          be set if the TCP-port is not 119  (the  default).   The  ''-p''
          command-line option overrides $NNTPPORT.

   DISTRIBUTION
          Set  the  article header field ''Distribution:'' to the contents
          of the variable instead of the system default.

   ISO2ASC
          Set the ISO to ASCII charset decoding table character to use  in
          decoding an article text. Values can range from -1 to 6.

        -1     no conversion

        0      universal table for many languages

        1      single-spacing universal table

        2      table for Danish, Dutch, German, Norwegian and Swedish

        3      table  for Danish, Finnish, Norwegian and Swedish using the
               appropriate ISO 646 variant

        4      table with RFC1345 codes in brackets

        5      table for printers that allow overstriking with backspace

        6      table for IBM PC character set (code page 437)

   ORGANIZATION
          Set the article header field ''Organization:'' to  the  contents
          of  the  variable instead of the system default. If reading news
          on an Apollo DomainOS machine the environment variable  $NEWSORG
          has to be used instead of $ORGANIZATION.

   NEWSORG (DomainOS)
          DomainOS  specific,  same  as  $ORGANIZATION  on  other OSs (see
          above).

   REPLYTO
          Set the article header field ''Reply-To:'' to the return address
          specified by the variable. This is useful if you wish to receive
          replies at a different address.

   NAME   Overrides the full name given in the gecos-files in /etc/passwd,
          see also mail_address.

   REALNAME
          Same as $NAME.

   HOME   Pathname  of  the user's home directory. See environ(5) for more
          info.

   MAILER This variable has precedence over the  default  mailer  that  is
          used in all mailing operations within tin.

   MAIL   Full path to the user's mailbox.

   VISUAL This  variable  has  precedence  over  the default editor (i.e.,
          vi(1)) that is used in all editing operations within tin  (e.g.,
          posting,   replying,   follow-ups,  ...).  Evaluation  order  is
          ${VISUAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

   EDITOR If $VISUAL is unset, then this  variable  is  looked  up  for  a
          default  editor. If $EDITOR and $VISUAL are both unset, tin uses
          the systems default editor (i.e.  vi(1)) on  UNIX-systems).  See
          environ(5) for more info.

   AUTOSUBSCRIBE
          A  new  group  is  checked  against  the list of patterns; if it
          matches, tin subscribes the user to the  group  without  further
          query.   See  the  section  "NEWSGROUP LISTS & WILDCARDS" for an
          explanation of the valid syntax. For example, setting

          AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

          will automatically subscribe the user to all new groups  in  the
          comp.os.unix   hierarchy,   and   all  talk  groups  other  than
          talk.politics groups (which will be queried for  as  usual).  Of
          course  this  does  not  work  if tin is started with the ''-X''
          command-line switch.

   AUTOUNSUBSCRIBE
          Is handled like the $AUTOSUBSCRIBE variable, but groups matching
          the  list  are  unsubscribed  from  without  further  query. For
          example, setting

          AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

          will automatically unsubscribe the user from all  new  alt.flame
          groups  and all groups starting with u (university groups) other
          than UK groups (which will be queried for as usual).

   TMPDIR A pathname of a directory  made  available  for  tin  to  create
          temporary files.

   MAILCAPS
          This  variable  can  be used to override the default path search
          for mailcap(5) files. See also tin(5).

   NOMETAMAIL
          Set this variable  to  disable  the  use  of  metamail(1)  or  a
          replacement (e.g. metamutt).

   MM_CHARSET
          MIME character set used if not configured via the tinrc variable
          mm_charset.

   ISPELL Set this variable to point to ispell(1) or a replacement and its
          cmd-line options.

   PGPOPTS
          Define  any  additional  options  that  you wish to pass to your
          pgp(1) or gpg(1) program.

   PGPPATH
          Override the name of the pgp(1) directory in  $HOME  that  holds
          your keys etc..

   GNUPGHOME
          Override  the  name  of the gpg(1) directory in $HOME that holds
          your keys etc..

   LC_CTYPE
          This variable determines the locale(5)  category  for  character
          handling  functions. Usually it determines the character classes
          for  pattern  matching   character   classification   and   case
          conversion.  Currently this is not true for tin (which temporary
          unsets $LC_CTYPE  right  before  any  match  is  done  to  avoid
          confusion).     It's    value    should    be    of   the   form
          language[_territory][.codeset][@modifier].  See  environ(5)  for
          more information.

   LC_MESSAGES
          Formats  of  informative and diagnostic messages and interactive
          responses.    It's    value    should    be    of    the    form
          language[_territory][.codeset][@modifier].   See  locale(5)  and
          environ(5) for more information.

   LC_TIME
          Date and  time  formats.  It's  value  should  be  of  the  form
          language[_territory][.codeset][@modifier].   See  locale(5)  and
          environ(5) for more information.

   LC_ALL This variable overrides the value of the $LANG variable and  any
          other   $LC_   variable.  It's  value  should  be  of  the  form
          language[_territory][.codeset]. See locale(5) and environ(5) for
          more information.

   LANG   This variable determines the locale(5) category for any category
          not specifically selected with a variable  starting  with  $LC_.
          It's value should be of the form language[_territory][.codeset].
          See environ(5) for more information.

   LANGUAGE
          This variable defines a priority list for translations. Whenever
          a  translation  is  not  available  in the language selected via
          $LC_ALL or $LANG the next language from the list is tried.  It's
          value  should  be  of the form language:language[:language]. See
          environ(5) for more information.

   COLUMNS
          A decimal integer > 0 used  to  indicate  the  user's  preferred
          width  in column positions for the terminal screen or window. If
          this variable is unset or null,  the  implementation  determines
          the  number  of columns, appropriate for the terminal or window.
          When $COLUMNS is set, any terminal-width information implied  by
          $TERM will be overridden. Users and portable applications should
          not set  $COLUMNS  unless  they  wish  to  override  the  system
          selection   and   produce   output  unrelated  to  the  terminal
          characteristics.

   LINES  A decimal integer > 0 used  to  indicate  the  user's  preferred
          number  of lines on a page or the vertical screen or window size
          in lines. A line in this case is a vertical measure large enough
          to  hold  the  tallest  character  in  the  character  set being
          displayed. If this variable is unset or null, the implementation
          determines  the number of lines, appropriate for the terminal or
          window. When $LINES  is  set,  any  terminal-height  information
          implied   by  $TERM  will  be  overridden.  Users  and  portable
          applications should not set $LINES unless they wish to  override
          the system selection.

   TERM   The  type  of  terminal  in  use.  This  is used when looking up
          termcap sequences.  See environ(5) for more information.

   DISPLAY
          Display name, pointing to the X server; required for xface.

   WINDOWID
          Used for determining terminal's X window id; required for xface.
          Should be set by the terminal emulator.

   SHELL  The   pathname   of   the   user's  login  shell.  Used  to  set
          default_shell_command.

   XDG_RUNTIME_DIR
          The pathname of the user's dir to  put  non-essential  run  time
          files into.

SIGNALS

   tin handles a couple of signals:

   SIGHUP Terminate gracefully.

   SIGTERM
          Terminate gracefully.

   SIGUSR1
          Terminate gracefully but do not restore terminal (tty).

   SIGUSR2
          Write out ${TIN_HOMEDIR:-"$HOME"}/.newsrc-file.

SECURITY

   If  tin  is  started  in  debug  mode  (''-D  n'') it will create world
   readable files in $TMPDIR which may contain the users NNTP password  in
   cleartext.  On  multiuser-systems  $TMPDIR  should  be  set  to  a safe
   location before starting tin in debug mode (e.g.  TMPDIR=$HOME  tin  -D
   1).

CONFORMING TO

   tin   does   conform  to  the  Base  Definitions  volume  of  IEEE  Std
   1003.1-2008, Section 12, Utility Conventions (Utility Argument  Syntax,
   Utility Syntax Guidelines).

HISTORY

   tin  is  based  on  the  tass(1)  newsreader that was developed by Rich
   Skrenta and posted to alt.sources in March 1991; its first version  was
   released on August 23rd 1991.  tass(1) itself was heavily influenced by
   notesfiles a public domain UNIX version of PLATO  Notes,  developed  at
   the University of Illinois by Ray Essick and Rob Kolstad in 1982. For a
   version overview see
   <http://www.tin.org/history.html>.
