say-thanks - a little script which lets your users say "thanks" :) The idea is simple: include a 'say-thanks' executable with your application. People will see it, and (because they are curious hackers), run it. It will give them the chance to say something nice about your app. Neat, 'eh? For you, the developer, it's pretty simple too: you've just got to pick one of the existing 'say-thanks' scripts, preferably written in the same language as your application, then include it, along with a .thanksrc file, in your tarball.
Nothing to see here, move along.
