If more manpages are added in the future, they should be
added in the MAN_NAMES variable and that should be it.

Unfortunately the cmake "install(FILES ${MAN_FILES} TYPE MAN)" doesn't
seem to work right and just drops the manpage straight into
.../share/man/ rather than in a sectioned subdir, thus the ugly string
regexp mangling.
