Get all updated git repositories easily

Sometimes, you'll find yourself looking for the newest versions of some projects that you have to use in your own projects e.g: jQuery. I myself like to organize all those projects in one place so I can search for them easily. This is how I keep it organized:

1. Create a directory "git-repos" anywhere you want
2. Create an alias in .bash_profile: alias clone="cd /path/to/git-repos/ && git clone". You can now clone repositories with: clone git@server:project.git
3. Put the below git-pull-all.php script in git-repos directory
4. Finally, create an alias to issue the update: alias update-git-repos="php /path/to/git-repos/git-pull-all.php".
