@"
You can get the Posh-NVS module from
https://github.com/darkoperator/Posh-NVS
written by Carlos Perez, http://www.darkoperator.com
Download the ZIP and put the entire folder as Posh-NVS under your module folder

IMPORTANT NOTE: Remove all streams from the files in the module folder.  I used:
gci -Recurse |  Remove-Item -Stream *

If you fail to do this you may get an "Operation is not supported"
error importing the module.
