What does this bash line do?

[Tim Visher <tim dot visher at gmail dot com>]

Hi All,

I'm working on my bashrc and I found [this
line](http://pastie.org/844068) that I had copied out of /etc/skel via
cygwin.  I'm trying to create a platform agnostic bash configuration
in the spirit of .emacs.d with .bashrc and .bash_profile and one thing
I'm running into is that various locations change so I need to either
conditionally load them via `if [ ]` statements or possibly better yet
discover the platform I'm on and have a single conditional or set a
variable in the spirit of `(emacs-type)`.

My question then, is what exactly is this line doing?  Like I said, I
got it from my Cygwin install but it works very similarly at home on
Apple Bash w/ MacPorts underneath.  I understand this isn't strictly a
Cygwin question but I figure you all are bash experts anyway so why
not?
