please consider removing avahi-sharp from the archive. Upstream is dead,
the last release is from 2007 and it has been kept on life support in
Debian via NMUs over the last couple of years.
The package is currently RC buggy and I don't see a fix for #877038
without a major rewrite, porting everything to GTK3, which given the
upstream situation is unlikely to happen.
The only rdep is gshare, which has very low popcon scores and the
functionality of the application (sharing via FTP) is less important
then it once was.
I've CCed the maintainers of gshare in case they object to this removal.
