Civilint is a thin wrapper which calls jshint and PHP_CodeSniffer (with the 
coder ruleset).

Code-style tests ensure a consistent layout across all of the codebase, and 
they also identify some unsafe or confusing coding patterns. While working on a 
patch, you should run civilint to determine if the pending changes comply with 
style guides. 

Note that civilint may be invoked a few different ways:

```bash
civilint # (no arguments) – Check style of any uncommitted changes.
civilint some/file.php # Check style of a specific file (or list of files).
git diff --name-only origin/4.6.. | civilint - # Check changed files
```
