NAME

   use - Frontend to the Usepackage Environment Manager

SYNOPSIS

   csh and derivatives:
           source /usr/share/usepackage/use.csh

   bourne shell and derivatives:
           source /usr/share/usepackage/use.bsh

   korn shell:
           . /usr/share/usepackage/use.ksh

   use [-vs] [-f file] package ...

   use -l

DESCRIPTION

   Usepackage  is  an  environment  management program. It is based on the
   principle of packages - collections of executables that share a  common
   set  of  necessary  environment  variables,  such  as  PATH, MANPATH or
   LD_LIBRARY_PATH.

   For  each  given  package,  use  sources  the  appropriate  environment
   information  into  the  current  shell.  The environment information is
   specified in a configuration file, see usepackage(1).

   OPTIONS
   -v     Output verbose information to the standard error stream.

   -s     Silence warnings for un-matched packages. This is  useful  in  a
          shell  rc  script when a package is known not to be available on
          all architectures that the shell is used on.

   -f file
          Specify an alternate initial configuration file.

   -l     List available packages and groups.

FILES

   /usr/share/usepackage/usepackage.conf
                  The default configuration file.

   /usr/share/usepackage/use.csh
                  Shell setup for csh and derivatives.

   /usr/share/usepackage/use.bsh
                  Shell setup for bourne shell and derivatives.

   /usr/share/usepackage/use.ksh
                  Shell setup for ksh.

   /usr/bin/usepackage
                  The underlying Usepackage executable.

ENVIRONMENT

   Other than the reading and re-definition of environment  variables  for
   package  setup,  use  also uses the following environment variables for
   user configuration:

   PACKAGES_PATH  Colon-separated path  list  giving  the  directories  to
                  search  for  configuration  files. Shell-style tilde (~)
                  user-directory escapes are expanded.

   HOME           If present in the environment, this is used  to  provide
                  the expansion for the tilde (~) user-directory.

   SHELL          If  present  in the environment, the last path component
                  of this is used for  shell  matching  (see  SYNTAX)  and
                  detecting the style of environment output that should be
                  used, see usepackage(1).
