The point now is that, while working on it, I needed some module to parse command-line options and “subcommands” (like git commit, svn update, etc.). As it’s written in Perl, I had a look at CPAN to see if I could see anything. The most promising module was App::Rad, but it lacked a couple of things that were very important for me: my idea was “declaring” all the possible commands and options and have the module do all the work for me (generating the help pages and the default --help implementation, generate the program help subcommand and so on). App::Rad didn’t have that, and it didn’t seem to me like that was the direction they wanted to go to with the module. But I figured I’d drop the author an e-mail anyway and see if he liked the idea so I could start adding support for all that…

And boy was that a good idea. He replied a couple of days later, and said that they had liked the idea so much that they had implemented it already (that’s why he took a couple of days to reply), and he sent me an example of the new syntax they had introduced and asked if that was what I was thinking. And not only that, but they added me to the list of contributors just for giving the idea! That completely made my day, free software rocks!
