	* Makefile.am (EXTRA_DIST): dist cleanup-man-pages.sh so it's in
	the tarball if packagers want to run it

	* cleanup-man-pages.sh: Add a script which munges all the internal
	API man pages out of the Doxygen output. This reduces the size of
	the installed man pages from 7 to 2 megs, and avoids
	namespace-polluting pages. Right now (like Doxygen) this script
	isn't in the build, it's something packagers can do manually.

+## generated by Doxygen.  This brings the man pages down from 7 megs
+## to 2 megs and avoids namespace-polluting man pages.  It's probably
+## pretty specific to GNU utilities. Patches gladly accepted to make
+## it work without them.
+
+## You would run this after building dbus and after running "doxygen
