Almost a year ago, I wrote CPAN tutorials. It isn't an original work, it's a derivative of RubyGems Guides, only "translated" to Perl world. I failed to publish it anywhere until now. I'll be happy if anyone finds it useful in any way which the license allows. And I'll be even happier if I get any feedback.
And here it is: http://tynovsky.github.io/cpan-tutorials/
