+"""Checks JavaScript files for common style guide violations.
+
+gjslint.py is designed to be used as a PRESUBMIT script to check for javascript
+style guide violations.  As of now, it checks for the following violations:
+
+  * Missing and extra spaces
+  * Lines longer than 80 characters
+  * Missing newline at end of file
+  * Missing semicolon after function declaration
+  * Valid JsDoc including parameter matching
+
+Someday it will validate to the best of its ability against the entirety of the
+JavaScript style guide.
+
+This file is a front end that parses arguments and flags.  The core of the code
+is in tokenizer.py and checker.py.
