Usage: run_doxygen --mode=MODE --host_alias=BUILD_ALIAS [<options>]
<v3-src-dir> <v3-build-dir> <shortnamesp>
MODE is one of:
html Generate user-level HTML library documentation.
man Generate user-level man pages.
xml Generate user-level XML pages.
latex Generate user-level LaTeX pages.
BUILD_ALIAS is the GCC build alias set at configure time.
Note: Requires Doxygen ${DOXYVER} or later; get it at
