# This script allows running Raft as a resizable and movable window
#
# The first thing that needs to be done is to save this to your computer
# as a *.ps1 file (that last character is the number 1). This is the
# extension for powershell scripts, a terminal scripting language
# that comes standard with WindowOS.
#
# The next thing to do is set up your computer to run powershell scripts.
# For reference:
# https://www.windowscentral.com/how-create-and-run-your-first-powershell-script-file-windows-10
# "
#   If you want to run a script file on PowerShell, you have to change the execution policy on Windows 10.
#
#   To change the execution policy to run PowerShell scripts, use these steps:
#
#   Open Start.
#   Search for PowerShell, right-click the top-result and click the Run as administrator option.
#   Type the following command to allow scripts to run and press Enter:
#
#   Set-ExecutionPolicy RemoteSigned
#
#   Type A and press Enter.
# "
#
# Then run Raft, and then run this script.
# Note that you can't double click its icon - to run it from the file
# explorer, the script needs to be right clicked, and select
# "Run With Powershell"
