Replacement for CGI.pm escape and unescape

[cfaust-dougot]

Hi All,
 
I'm running the latest mp2 with Libapreq. 
 
Is there some method to duplicate CGI.pm's escape and unescape methods? I found 
escape_path, but obviously that isn't the same thing. I'm trying to remove 
CGI.pm from all my code and these are the last 2 things I need to take care of.
 
TIA!
