I asked not that long ago in CB where to find those docs
in reply to Re: perldoc deleted modules
in thread perldoc deleted modules
That is not the question. Question is why they were deleted. Are they old enough? If yes, then I would say Perl Cookbook is also old. I would say CPAN contains old modules. I would say filter out all of the things in that documentation of 70000 words.
Perldoc is not a book which you have to complete reading for an examination. It is something to keep for reference and use whenever required. Uninterested one would not read something in which he/she is not interested. Surprising...
