#Companion code for the blog https://cloudywindows.com

#Usage - if you do not have the ability to run scripts directly from the web,
#        pull all files in this repo folder and execute, this script
#        automatically prefers local copies of sub-scripts

#Completely automated install requires a root account or sudo with a password requirement

#Switches
# -includeide         - ignored, as Amazon Linux does not have a desktop environment
# -interactivetesting - ignored, as Amazon Linux does not have a desktop environment
# -skip-sudo-check    - use sudo without verifying its availability (hard to accurately do on some distros)
# -preview            - installs the latest preview release of PowerShell side-by-side with any existing production releases

#gitrepo paths are overrideable to run from your own fork or branch for testing or private distribution
