Since I once in a while post powershell scripts on my site, I like that fact that I can have them color highlighted for better readability, so I played around with several different syntax highlighters, but none of them was able to do powershell, so I created a brush for Syntax highligther plus.
This is my initial attempt, updated to work with Syntax Highlighter plus 2

I modified a version made by Joel Bennet to work with version 2 as well.

Be aware that compared to version 1 of the brushes you can no longer have specific css settings in the brush (previously you could define font/colors for different datatypes/keywords in the brush), this has been changed inversion 2 because of a new theme options.
