# Originally hacked together by Phil Edwards <pme@sources.redhat.com>

# We could check that the version of doxygen is >= this variable, but that's
# just a pain.  Punt for now and rely on the maintainer to read this.  :-)

Usage:  run_doxygen --mode=MODE [<options>] <src-dir> <output-dir>
      MODE is one of:
          maint          Generate maintainers' documentation (lots more;
                             exposes non-public members, etc).
          user           Generate user-level library documentation.

      more options when i think of them

Note:  Requires Doxygen ${DOXYVER} or later; get it at
