Contenthooks is a Google AppEngine service to validate commits to repositories hosted on Google Code.

This service uses Post-Commit Web Hooks to trigger a customizable set of common style validation tools against a commit's list of modified files. Failed validation results are emailed to the revision author.

Supported validators:

• max file size
• xml validity
• forbidden strings
• utf8
• utf8 BOM detection
