GitHub-Backup
=============
By Chris Lockfort (devnull@csh.rit.edu) (Github username: Clockfort)
Idea By Chris Lockfort (devnull@csh.rit.edu) (Github username: Clockfort)
Python version By Anthony Gargiulo (anthony@agargiulo.com) (Github username: agargiulo)
GitHub-Backup makes a local backup copy of all of a github user's (or github organization's) repositories.
Usage
-----
"./github-backup.pl USERNAME BACKUP_DIRECTORY"
"./github-backup.py USERNAME BACKUPDIR [-c|--cron] [-h|--help]"
Then, put it in a cron job somewhere and forget about it for eternity.
