perforce_sync_stream_depots.ps1

#
# A powershell script for automatically looping over all perforce helix stream depots and 
# calling 'p4 sync' on each one to sync the latest files to the local workspace. 
# If a new stream depot is detected, the script also creates a new workspace and 
# local directory for the stream depot to get synced to.
