# Things that could be implemented ...
# Get-LocalWeather https://joeit.wordpress.com/ # Bit of fun, but pull weather info to console
#
# Not built:
# AddTo-SystemPath, RemoveFrom-SystemPath, AddTo-UserPath, RemoveFrom-UserPath (might not want these, build into the generic 'path' function)
#
# ToDo: Enable network access on all systems
# ToDo: Make all networks private (to make compliant with various things like VPN etc)
# ToDo: Enable RDP on all systems
# ToDo: Must add PSReadLine to PowerShell 5.x on Win 7 etc, by default is not installed. Need it for many of the standard console behaviours, Ctrl+R etc

# Remember that PowerShell is processed sequentially, so cannot put functions below where they are called.
# If top down coding is wanted in PowerShell, can use a 'Main' function:
#
# function Main {
# MyFunc1
# MyFunc2
# <other code ...>
# }
#
# function MyFunc {
# "Hello, World!"
# }
#
# Main
#
#
# Or using a scriptblock, put the body of your script in a scriptblock at the top:
#
# $block = {
# Echo "Here is where the main body of my script is"
# Echo "About to call my function"
# MultiplyByTwo 5
# Echo "Done calling my function"
# }
# function MultiplyByTwo([int] $num) { 2 * $num }
# function MultiplyByTen([int] $num) { 10 * $num }
#
# # Finally, innvoke the script with a single line at the bottom
# & $block
