http://cpansearch.perl.org/src/PRAVUS/Authen-CAS-Client-0.08/LICENSE 'This software is information. It is subject only to local laws of physics.'
Can you please confirm whether it is free or non-free?
I have no expertise to answer the posed question, but I have to mention that the premise statement is evidently false — ‘Authen CAS Client’ is by no means a mere ‘information’, it does include both nontrivial program code and texts in human language.
P. S. Thanks for a nice specimen for my modest collection of silly licences.
