When Larry says a virtue is to be Lazy, he didn't mean to be a Lazy SoB. Part of programming is to write the README files so users know how to use the stuff you write. Not everyone can read Perl, or read everyones style of Perl and the README helps to remedy this. If you used POD within your script, you could extract it.. otherwise, it would be good practice, especially for a student, to write a decent README for your script. Sometimes when writing how to use a script you can see things that don't make sense, aren't obvious, and things that in general would be good to fix. So, do everyone a favor, and write your README.. it is not programming, but still the work of any respectable programmer (IMO).
