// File:
// clicks.m
//
// Compile with:
// gcc -o clicks clicks.m -framework ApplicationServices -framework Foundation
//
// Usage:
// ./clicks -x 10 -y 10 (or whatever coordinates you want)
// it will click and release, but you can edit the code for the desired effect
//
// Yes, it is an ugly mix of Cocoa and Carbon.
// Yes, it could be rewritten in only a few lines of code.  
// Whatever.
