You should also check to see if your option is listed in the GNU Coding Standards Option Table. Don't forget to support --help and --version!

Other than that, nice intro.

    That statement only applies to GNU/Linux systems, or at least systems that use the GNU Binutils. Most commercial UNIX vendors don't have long option support in their Binutils. Sun and HP's versions of tar don't support long arguments, but FreeBSD and Linux support both forms of arguments.

    While the choice of which arguments your programs accept is your choice, many people choose to follow the standard their OS vendor uses. I think that the table showing only the short arguments is good because short arguments is more of a standard then GNU-Style arguments, but I think that including a link to GNU Coding Standards Option Table, with an explaination that these are used mainly on GNU/Linux or GNU Binutils systems would be useful.


      Ah, but this is Perl, you're supposed to be thinking cross platform. And what is more cross platform than GNU?

      I'd recommend looking at the table, and using what's on there unless you have a good reason not to.
