Have been doing a lot of university work lately and for that extra presentational edge it's nice to drop some syntax highlighted code into your documentation. I found a TextMate Bundle to allow just that 
However its in a Git repository meaning using something like MacPorts to fetch the source of and compile the Git CLI client and all its other dependencies (Curl, OpenSSH, Perl). So for the motivationally challenged amongst you I have done the time consuming work for you.
