This consists of just one single ruby script, which runs shell commands assuming
that the current PATH has all dependencies set up correctly. Unfortunately, this
somewhat breaks functional purity as the command won't work correctly in
environments that do not contain git, darcs or diffutils.
During the patchPhase we replace all those dependencies directly in the ruby
source code, rather than creating a wrapper. Afterwards we run a checkPhase
which not only checks whether we caught all the dependencies (PATH=) but also
checks if the conversion has been done correctly.
