- code review
- integrate with xmldumps-backup
- reasonable handling for file-related errors (file not found, access denied, etc.); right now, the application just crashes
- Tracking bug
- better compression for metadata and indexes
- compress indexes using varints (or LZMA?)
- add index for named users
- compress list of revision ids of a page using varints
- store parent id as a varint difference from revision id
- add index for namespaces
- see if it's possible to tweak LZMA (language-specific Huffman tables?)
- library for binding with other languages
