Mirroing GitHub

As you may (or may not) know, I swichted a while back from self-hosted mercurial repositories to GitHub. While I'm happy with GitHub, I still want to have my favourites repositories available at hand (if/when GitHub is down).

Although there are already a lot of "backup script" on the net I wanted something very stupid and simple which integrate well with FreeBSD, so I wrote a periodic(8) script.

Show me the code

The script is straightforward. Once you've completed your /etc/rc.conf.local root is going to have a nice report in your "daily run output" e-mail.

It could be improved to also pull wiki and/or issues etc, if you come up with some code let me know !

/usr/local/etc/periodic/daily/999.git-pull
