3.1.1 Tasks Options
-------------------

Task options specify the task a2ps will perform.  It will not print, it
executes the task and exits successfully.

 -- Option: --version
     print version and exit successfully.

 -- Option: --help
     Print a short help, and exit successfully.

 -- Option: --copyright
     Display Copyright and copying conditions, and exit successfully.

 -- Option: --guess
     Act like 'file' does: display the (key of the) type of the FILES.

     For instance, on a 'C' file, you expect it to answer 'c', and upon
     a PostScript file, 'ps'.

     This can be very useful on broken systems to understand why a file
     is printed with a bad style sheet (Note: Style Sheet Files).

 -- Option: --which
     Look in the library for the files which names are given as
     arguments.  For instance:

          ~ % a2ps --which bw.pro gray.pro
          /usr/local/share/a2ps/ps/bw.pro
          /usr/local/share/a2ps/ps/gray.pro

     If there are several library files matching the name, only the
     first one is reported: this allows to check which occurrence of a
     file is used by a2ps.

 -- Option: --glob
     Look in the library for the files which names match the patterns
     given as arguments.  For instance:

          ~ % a2ps --glob 'g*.pro'
          /usr/local/share/a2ps/ps/gray.pro
          /usr/local/share/a2ps/ps/gray2.pro

 -- Option: --list=TOPIC
     Display a report on a2ps' status with respect to TOPIC, and exit
     successfully.  TOPIC can be any non-ambiguous abbreviation of:
     'defaults'
     'options'
          Give an extensive report on a2ps configuration and
          installation.

     'features'
          Known media, encodings, languages, prologues, printers,
          variables, delegations and user options are reported.  In a
          word, anything that you may define.
