## This script cleans up private/internal API from the man pages
## 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
## Doxyfile"
