1) look at the existing Unicode:: modules in CORE and decide if your module belongs in CORE (ask p5p if necessary)
2) if not, pick a namespace and name
3) decide how to generate the CPAN boilerplate files (I use makemaker) there is a non-trivial amount of work to make a nice CPAN module
these days!
4) add some tests
5) try your distro on different machines and when you're happy request a CPAN account and upload it.
6) wait for CPAN testers to score it and fix it
7) bask in the glory of being a CPAN contributor, along with the other 10,000 members! :)
