Powershell Quick Tip - How do I get the Powershell Version?

I often get asked how to determine the version of Powershell running in an environment.  I wish it was a simple as just typing "ver", but alas, it's slightly more complex than that.  You'll need this statement:

$PSVersionTable.PSVersion

This will output the version table looking like this:

PS C:\> $PSVersionTable.PSVersion

Major  Minor  Build  Revision
-----  -----  -----  --------
4      0      -1     -1
