Learning perl libraries

[rakesh sharma]

Hi
I am a new to perl.Wanted to know how to master some of the daily used perl 
libraries.Most of the examples are different in usage, some are OO and others 
are scalar.I want to learn the OO way of perl.Any tips? Right now I open the 
file and see the usage or prod the net. But the learning remains 
incomplete.Most of the perl books speaks stuffs in general and do not target 
the libraries.
thanks,rakesh
