What does this part do: 
$repl{$1}||$1/ge;

[download]
I know the 'g' is global but I couldn't find what the 'e' is. Also, I couldn't find any info for the '||'.

Thanks in advance.

    It's in man perlop.

    Amazingly, that's also in man perlop.

      Let's see if I did my homework right.

      An "/e" will cause the replacement portion to be treated as a full-fledge Perl expression and evaluated right then and there.

      An "||" Logical "OR" if the left expression true, then right is never evaluated.

      I think I got a handle on it now. Thanks for the pointers and making me do the homework ;-)
