- configure --help lists non-default documentation options.
Looking around the web, this seemed to me to be what most projects do.
Listed options are --without-doxygen, --enable-html-doc &
--disable-man-pages.
- configure warns on inconsistent options e.g. --without-doxygen by itself
warns man pages will not be built.
- configure.ac re-ordered so --without-doxygen overrides --enable-any-doc.
If html is requested, `make install` installs it in htmldir.
