gccjs
A simple build tool that uses Google Closure Compiler's Java API to watch files in IDE mode for faster type checking. In watch mode, it integrates error reporting into OS X Lion's notification system using node-terminal-notifier. It also contains special minification rules for WebGL code including GLSL minification (run gccjs -o in the example folder to see it in action).
Options:
--check (-c) Run checks (some checks only work with --optimize)
--help (-h) Displays this message
--no-warnings (-e) Treat warnings as errors
--optimize (-o) Optimize and minify (default just links to sources)
--project (-p) FILE The project file (defaults to project.json)
--watch (-w) Builds every time a file changes, implies --check
