hamsterdb 0.4.5

hamsterdb is a database engine written in ANSI C. hamsterdb supports a B+Tree index structure, uses memory mapped I/O (if available), and can create in-memory databases.
Main features:
- B+Tree index with variable length keys
- Configurable page size and cache size
- ANSI-C implementation, should be portable on all platforms, also embedded
- Uses memory mapped I/O for fast disk access (but falls back to read/write if mmap is not available)
- Uses 64bit file pointers
- Endian-independent (not tested, though)
- Support for in-memory-databases
Enhancements:
- This release implements "record number" databases; these databases behave like "auto-increment" tables in SQL.
- The keys of new records are automatically assigned and incremented with each insert.
- Also, a few minor bugs were fixed, and some optimizations took place; the generated database files are much smaller now.
