Powershell Comments
Comments will not be executed by Powershell.
Comments can be added to explain the Powershell, or to make the code more readable.
Single line comments start with #.
The following example uses single line comments to explain the code:
Like other languages powershell also supports single line and multi line comments.
Initially in PowerShell V1 there's only # to make the text after it a comment.
Starting PowerShell V2 Microsoft come up with block comments (multi-line)
        can be used more specifically for SYNOPSIS, DEsCRIPTION,
        NOTES, LINK  help comments.
        
        
Script example:
        
            $greeting = "Hello"
            # This line is single line comment.
            
            # This line is second line comment.
            
            $name = read-host "What is your name?"
            # This comment line is new.
            
            "$greeting, $name!"
        
        
            Begin the comment with the <# tag, and end the comment with the #>
                tag:
<# this is a comment 
   on several
   different
   lines
   #>
