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

#call this code direction from the web with:

#bash <(wget -O - https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-amazonlinux.sh) ARGUMENTS

#bash <(curl -s https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-amazonlinux.sh) <ARGUMENTS>

#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 - the script is being run headless, do not perform actions that require response from the console

# -interactivetests - requires a human user in front of the machine - loads a script into the ide to test with F5 to ensure the IDE can run scripts

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