If you're working on a distant archive and you're behind a firewall, you
might need to prefix all your commands with something like
runsocks. Of course, this can be done manually in all your
command settings, but Patcher offers you a simpler way to do it.
There is a project option named :pre-command which can be used
for this kind of thing. It must be a string that will be prepended to
all operations performed by Patcher.
