I wrote an answer on SO with some PowerShell code examples, but there's no syntax highlighting. There are currently 10,898 _{[as of 07/10/2013]} questions tagged powershell on StackOverflow. Please add prettified syntax highlighting to Powershell questions.

These are the one's I experimented with in my original testing.

<!-- language: lang-ps-->

<!-- language: lang-ps1-->

<!-- language: lang-powershell-->

<!-- language: lang-posh-->

Side Note: there are only 1,244 _{[as of 07/10/2013]} questions tagged dart on StackOverflow, and it is already supported
