|Keep It Simple, Stupid|
.... you seem to be under the misconception that there is ORDER in all of this module stuff.... you must be coming from a Java background in the universites.. :-)
...this is the way it works.... modules are just giant code efforts to do some task, that everyone previously was doing with separate disparate scripts.... eventually some smarter coders but the code into packages to make it easier for others to use....but there is no rhyme nor reason to what makes it to a module, or even if it works anymore.....
i don't think anyone in the Perl community wants to go thru all the modules out there, and write a book catagorizing what they do for you
...as to what Perl can do for you, it is only limited by your ingenuity and your knowledge of what a computer system can be used for.
...modules are just encapsulated code blocks....if you want to know what they do...look thru all the entries on CPAN, and start downloading and running the examples.....i can't even count the number of times that I've done:
I'm not really a human, but I play one on earth.
