+.SYNOPSIS
+
+Strips comments and extra whitespace from a script.
+
+PowerSploit Function: Remove-Comment  
+Author: Matthew Graeber (@mattifestation)  
+License: BSD 3-Clause  
+Required Dependencies: None  
+Optional Dependencies: None  
+
+.DESCRIPTION
+
+Remove-Comment strips out comments and unnecessary whitespace from a script. This is best used in conjunction with Out-EncodedCommand when the size of the script to be encoded might be too big.
+
+A major portion of this code was taken from the Lee Holmes' Show-ColorizedContent script. You rock, Lee!
+
+.PARAMETER ScriptBlock
+
+Specifies a scriptblock containing your script.
+
+.PARAMETER Path
+
+Specifies the path to your script.
+
+.EXAMPLE
+
+$Stripped = Remove-Comment -Path .\ScriptWithComments.ps1
+
+.EXAMPLE
+
+Remove-Comment -ScriptBlock {
+### This is my awesome script. My documentation is beyond reproach!
+      Write-Host 'Hello, World!' ### Write 'Hello, World' to the host
+### End script awesomeness
+}
+
+Write-Host 'Hello, World!'
+
+.EXAMPLE
+
+Remove-Comment -Path Inject-Shellcode.ps1 | Out-EncodedCommand
+
+Description
+-----------
+Removes extraneous whitespace and comments from Inject-Shellcode (which is notoriously large) and pipes the output to Out-EncodedCommand.
+
+.INPUTS
+
+System.String, System.Management.Automation.ScriptBlock
+
+Accepts either a string containing the path to a script or a scriptblock.
+
+.OUTPUTS
+
+System.Management.Automation.ScriptBlock
+
+Remove-Comment returns a scriptblock. Call the ToString method to convert a scriptblock to a string, if desired.
