Software is:

doing not more and not less than what the user needs
- Every feature is implemented in the most simple and straightforward form: keep it simple, fast, and clear
made for users capable of reading and customizing its source code
- Source code can be read by users in one evening
- External configuration is not necessary and discouraged
- User manual documentation is not necessary, hacking documentation is encouraged (via HACKING.md)
distributed as source code, compiled by the user
not meant to be developed forever and its final state should be described by its feature set from the beginning
extended either by the user directly, or by applying source code patches distributed as diff files
- It is encouraged to share your extensions with others who can find it useful
