Usage:  run_doxygen --mode=MODE [<options>] <v3-src-dir> <v3-build-dir>
      MODE is one of:
          user           Generate user-level HTML library documentation.
          maint          Generate maintainers' HTML documentation (lots more;
                             exposes non-public members, etc).
          man            Generate user-level man pages.

      more options when i think of them

Note:  Requires Doxygen ${DOXYVER} or later; get it at
       ftp://ftp.stack.nl/pub/users/dimitri/doxygen-${DOXYVER}.src.tar.gz
