gl-system-install -- system-wide install program

(as if we didn't already have enough programs with the word "install" in
their names!)

Anyway, this does what an RPM or a DEB would do -- basically implement
the instructions in Appendix C of doc/0.

You can use this to do a system-wide install if your distro isn't as
smart, forward-looking, and uptodate as Fedora ;-)

Clone the repo somewhere, cd to it, and run, for example:

    sudo src/gl-system-install /usr/local/bin /var/gitolite/conf /var/gitolite/hooks

or something like that.  See doc/0 for details.  Run without arguments
for help.
