I originally posted it to PM as it's one of the few active Perl forums, so I hoped there would be people with PDL experience around.
I wasn't too sure of the reaction or whether people would be interested in helping. Seems like I have my answer now! :P
I have no objection to putting the completed documents on Github. They are in POD format, so could easily add a makefile to generate html/pdf/etc.
Thanks to everyone who is contributing solutions.
