Grunion

Run multiple commands using glob patterns.

Why Grunion?

• Sometimes you want to run multiple scripts in separate processes.
• node, babel-node only run one file at a time.
• tape and blue-tap run globs of files in a single process.
• AVA is not a generic runner.

Features

• Runs one shell command per file, based on a extended glob (see globby).
• Defaults to running node concurrently.
• Use complex commands using template strings.
• Doesn't require bash scripts.
• Prefers locally installed binaries by default (see execa).
• Promise API interface.

Tested on mac, windows cmd, and cygwin
