def format_filename(s):
    """Take a string and return a valid filename constructed from the string.
Uses a whitelist approach: any characters not present in valid_chars are
removed. Also spaces are replaced with underscores.
 
Note: this method may produce invalid filenames such as ``, `.` or `..`
When I use this method I prepend a date string like '2009_01_15_19_46_32_'
and append a file extension like '.txt', so I avoid the potential of using
an invalid filename.

This fabric file makes setting up and deploying a django application much
easier, but it does make a few assumptions. Namely that you're using Git,
Apache and mod_wsgi and your using Debian or Ubuntu. Also you should have 
Django installed on your local machine and SSH installed on both the local
machine and any servers you want to deploy to.

_note that I've used the name project_name throughout this example. Replace
this with whatever your project is called._

HOWTO: Using FileMerge (opendiff) with Git on OSX

FileMerge (opendiff) can really come in handy when you need to visually compare merging conflicts. Other times it's just a nice visual way to review your days work.

The following method works by creating a simple bash script (git-diff-cmd.sh) that sets us up with the proper command line arguments for Git to pass off files to FileMerge.
