Run multiple linters efficiently.
Usage:
polylint [-h] [-v] [-F] [-S]
Options:
-h show this help message
-v more verbose output
-F fail on first error
-S only run on files that are staged with git
Linters can be configured in a file called .polylintrc in the following format:
py:flake8 --exclude tests %s
js:jshint
css|scss:stylelint "%s"
