Multiline comment in PowerShell
In PowerShell v2 and newer, use the following syntax for the multiline comments:
<# a
b
c #>
The multiline comment in PowerShell should work.
If not, try this...
# This is
# a
# multiline comment.
or
<#
This does works for me.
#>
If it doesn't work, try to check if you have the correct version of PowerShell.
