Required:
- open source license
- easy to install on all major distros
- low overhead for large number of repositories (one per document)
- fast for simple operations (create repo, checkout any version, commit to any branch, create branch)
Useful:
- good documentation
- easy to set up / use
- good delta compression
- low-level bindings (Python or at least C)
- atomicity / "global" (per repo) version ids (so we can store entire directories)
Don't care:
- rename support (filename is artificial)
- copy support
- repository mirror support (internal usage only)
- change propagation to parent repository
- permission support (handled by higher level)
- changesets/transactions (atomic groups of modifications)
- blame (not useful for most of the files anyway)
- partial checkouts
- per-file commit message
- networking support
- portability (to non-POSIX)
- web interface
- GUI
