Sounds good. Also include examples of the right way to do $output=qx/command/<<EOF input EOF instead of $output=qx/command<<EOF input EOF / and [I have no idea] instead of $output=qx/echo $input|command/ i.e., how to input small things to qx without disrupting other parts of the program or relying on /bin/sh constructions to get the input connected.
