Subject: Packages::Dispatcher: create from code from dispatcher.pl
X-Git-Url: https://git.deb.at/w?a=commitdiff_plain;h=48bb7c72e18783e72ba26002c794e71c15557037;p=deb%2Fpackages.git

Packages::Dispatcher: create from code from dispatcher.pl

This is currently only a copy with some small formatting changes.
But this should benefit our mod_perl cleaness and I intend to
wrap that up somewhat nicer in the future, too.
