Use shell commands in your gulp or vinyl pipeline. Many command line interfaces are built around the idea of piping. Let's take advantage of that in our Gulp pipeline! To use gulp-run, simply tell it the command to process your files; gulp-run accepts any command you could write into your shell, including I/O redirection like python < baz.py | cat foo.txt - bar.txt. Additionally, node_modules/.bin is included on the path, so you can call programs supplied by your installed packages. Supports Unix and Windows.
