   mytool is a my map file manipulation program in the yudit distribution.
   It can generates so-called binary nbit ( my ) map file that can map any
   sequences of bytes into any sequences  of  bytes.  These  sequences  of
   bytes  can  be  grouped  into  1,2,4 and 8 bytes long words.  The input
   sequence length may be different from the matched sequence length. 'i /
   'n  ->  'b specifies that the word 'in' produces 'b' but only the 'i is
   consumed from the input buffer.

   It can also generate a so-called binary umap file, that maps  8  or  16
   bit  single  words into 16 bit single words and it contains the reverse
   map too.

   It can also disassemble the input map and produce a mys source file.

   The input can be a binary umap file, a my file, mys file a  uni  and  a
   kmap  file for yudit. It is recommended that all kmap files use the new
   mys format because it gives more freedom to define the mapping.

   The yudit distribution has a simple document  yudit/doc/my.doc  on  the
   binary    map    formats,    and    a    source   file   example   file
   yudit/mytool/my/example.mys please refer to this for more details.


   -info  prints out a small information on the current map.

   -test  lets you test the map interactively.

          show alls the keys in the map file.

          builds a state machine in the encoding part of the map file. The
          resulting map file can be written to disk with the -write option
          The resulting my files can contain state  machines  to  speed-up
          conversion.  A  state machine based my file can manifest 10%-70%
          performance improvement, so it may  be  desirable  for  encoding
          fontmaps.   For fontmaps the bumap format might be better suited
          where only one character and not a sequence of  characters  need
          to be mapped.

          builds a state machine in the decoding part of the map file.

   -strip strips  off  the  state machines from the map files.  The -write
          option can be used to save the new map file.

          option performs a simple benchmark test  on  the  map  file,  to
          compare  speed  of  simple,  state  machine based and binary map
          based map files.

          option strips all comments from an input source file  of  format
          mys kmap uni.  It does not strip comments from a binary file.

   -name new-name
          assigns a name to the map file.

   -comment new-comment
          assigns a comment to the map file.

   -type new-type
          assigns  a  map  file  a  distinctive  type, that can be kmap or
          fontmap but it is only  informative.  Keymaps  can  be  used  as
          fontmaps and vice versa.

   -write output-file
          writes  the data into an output file.  mytool never modifies the
          original file. All modifications should be explicitly saved with
          the  this  option.   Never  specify  the same file for input and

   -my input-file
          load a  binary  map  file.  Only  one  of  this  option  can  be

   -mys input-source-file
          load a source file.

   -rmys input-source-file
          load  a  source  file  and  reverse  it  -  make  encoding  from
          decoding and vice versa.

   -kmap input-source-file
          load a source file in kmap format.

   -rkmap input-source-file
          load a  source  file  and  reverse  it  -  make  encoding   from
          decoding and vice versa.

   -uni:l,u input-source-file
          load a source file in Unicode Consortium format. This format has
          the local code in  column  l,  and  unicode  in  column  u.  The
          numbering of columns start from 0.

   -runi:l,u input-source-file
          load a source file in Unicode Consortium format and reverses it.
          Make encoding from decoding and vice versa.

   -8     option can be used with the -uni or -runi options. It  specifies
          that the input is 8 bit and not 16 bit.

   -high  option  can be used with the -uni or -runi options. It specifies
          that the key should be or'ed with 0x8080.

   -low   option can be used with the -uni or -runi options. It  specifies
          that the key should be and'ed with 0x7f7f.

   -convert output-file-format
          converts  the  map  file  to  a  format.  It is useful only when
          combined  with  -write  otion.   The  possible  formats  are  my
          -binary,  mys  -source,  myc  -my-c-source, umap -umap-c-source,
          bumap -binary-umap formats.  For maps where only a single  8  or
          16  bit  local code  should be converted into 16 bit unicode and
          vice versa, the umap file formats are recommended.  The c-source
          files are provided so that you can inlucde a full map into the c


    mytool prints out an error message and exits with a non-zero status on
   error.  If there is no error the exit status is zero.
