Puritan/Principles

Puritan is based on several fundamental principles.

1. Tools should be usable for both decentralized and centralized patterns of development.
2. People **will** want to make unpackaged changes to their builds.
3. Caching matters.
4. Interactive development matters.
5. Build reproducibility matters.
6. Error-detection, handling, and cleanup matter.
7. People working on the OLPC build system will become accustomed to git and python.
