8 June 2015: GoogleCL is currently broken due to the OAuth1 turndown, and likely to remain so. Thanks for your support over the years, and apologies for the lack of prior notice.
summary How to contribute to GoogleCL
Using
The easiest way to help is to use the program and file an issue when you find something that seems amiss. You can also give less structured feedback on the Discussion group
Developing
The easiest way to contribute code is to find (or submit) an issue in the Issues Tracker, write code that addresses the issue, then upload a subversion diff that patches the issue using upload-diff.py, included in the trunk of the repository. Be sure to check out the Discussion group and StyleGuide
Before we can use your patch, though, you have to sign something. * If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an individual CLA. * If you work for a company that wants to allow you to contribute your work to Google Data Python Client Library, then you'll need to sign a corporate CLA
