PEG.js is a simple parser generator for JavaScript that produces fast parsers with excellent error reporting. You can use it to process complex data or computer languages and build transformers, interpreters, compilers and other tools easily.

var peg = require('gulp-peg');

var paths = {

Uses tree along with a .gitignore file to filter results. Defaults to ignoring node_modules if no .gitignore can be found in the current directory or in the git repo's root directory.

Would be cooler if we knew exacty where .gitignore files made a difference. Even nicer if the output showed the status of files in Git (modified, unchanged, new, deleted etc).
