in reply to how to get documentation of perl modules
Our fine monk Juerd (who I still suspect of actually enjoying encoding issues, but that's besides the point) created an awesome redirect tool (in the likes of php.net) to look up the documentation fast.
When in need for the documentation of say the CGI module, type this in your browser's location bar: http://tnx.nl/CGI. If you want more than one, module, use a comma, like:
Of course, functions like map or split can be looked up too: http://tnx.nl/map, http://tnx.nl/split. And, sure, http://tnx.nl/perlunifaq will work.
