Blender Persona Script

BlendPersona.ps1

# Powershell 7
# Quick and Dirty tool to manage alternate Blender personas by 
# swapping out Startup.blend files.
#
# The general idea is tha you have a config BACKUP folder where you keep a 
# master copy of the general startup and your special startup files.
#
# For example... I have one Blend file that starts up without default cube and is setup
#  for Millimeters... (for making 3d printing models)  and it saves me the time of messing
# with UNITS and such.
#
# Example: My current settings folder in Windows 10 is:
# C:\Users\Willard\AppData\Roaming\Blender Foundation\Blender\2.93\config
#
# You WILL need to make edits to personalize this script
#  * Menu options...
#  * ConfigFolder
#
# Curts startup
