Is there a good place to provide usage information on this?

Best is to use argparse & make commandline flag instead of manipulating sys.argv
:-)

+  _AddToPathIfNeeded(_ESLINT_PATH)
+  import eslint
+
+  if len(sys.argv) == 1:
+    print eslint.RunEslintOnDirs(DIRECTORIES_TO_LINT)
+  else:
+    print eslint.RunEslint(sys.argv[1:])
