It's just /usr/bin/tg-admin.

Do you mean package the egg-info in with the rpm/deb? BTW, TurboGears
needs to be installed as rpm to ever be included in Fedora Extras (and
as .deb in Debian/Ubuntu land). This is a matter of policy. And people
are very wary about pollution of system directories like /usr.
Technically, files updated during runtime should go in /var (like
logs, state, and crap).

During runtime or during installation?
