Auxiliary tasks
---------------

  Kpsewhich provides some additional features not strictly related to
path lookup:

   * `--debug=NUM' sets the debugging options to NUM.  Note:
     Debugging.

   * `--expand-braces=STRING' outputs the variable and brace expansion
     of STRING.  Note: Path expansion.

   * `--expand-var=STRING' outputs the variable expansion of STRING.
     For example, the `mktex...' scripts run `kpsewhich
     --expand-var='$TEXMF'' to find the root of the TeX system
     hierarchy.  Note: Path expansion.

   * `--expand-path=STRING' outputs the complete expansion of STRING as
     a colon-separated path.  This is useful to construct a search path
     for a program that doesn't accept recursive subdirectory
     specifications.

     For one-shot uses of an arbitrary (not built in to Kpathsea) path,
     see `--path' in the previous section.

   * `--show-path=NAME' shows the path that would be used for file
     lookups of file type NAME.  Either a filename extension (`pk',
     `.vf', etc.) or an integer can be used, just as with `--format',
     described in the previous section.
