A certain compatriot who shall remain un-named...we'll just refer to him a 'jc'...no no that's too obvious, we'll call him 'wren,' has brought up the point that it is Perl, and not PERL as I have it written. So I figured I'd mention that I usually capitalize things that are Acronyms such as PERl being ( Pathologically Eclectic Rubbish Lister ), as well as capitalizing things that are named for references ( such as JAVA being named so because of the enormous amounts coffee imbibed by the writers ). So if you feel it should be Perl, then just squint, and it'll look that way.
Everyone has their demons....
