Compiler plugin for JavaScript Lint (http://www.javascriptlint.com), an (open source) checker for JavaScript syntax and coding techniques based on the Mozilla Firefox JavaScript engine.
This is similar to vimscript #2578 and vimscript #2729, but this script uses Vim's compiler infrastructure (so checks are triggered by the :make command), making its use consistent with syntax checkers for other languages.
