Puritan is based on several fundamental principles.
- Tools should be usable for both decentralized and centralized patterns of development.
- People **will** want to make unpackaged changes to their builds.
- Caching matters.
- Interactive development matters.
- Build reproducibility matters.
- Error-detection, handling, and cleanup matter.
- People working on the OLPC build system will become accustomed to git and python.
