module Rugged
A quick-n-dirty rugged swap-in. Since the rugged gem includes a native extension (libgit2), and since traveling-ruby does not yet include an updated version of it (the latest is 0.22.0b5 and we need >=0.23.0), we make a compromise, and make a traveling-ruby-based standalone release without rugged, but using plain git in order to install packages. So, users will have to have git installed on their machines.
So here's an absolutely minimal replacement for rugged (just for the functionality we need) wrapping the git command.
