Tinycdb 0.74 - Constant Database.

Tinycdb is a small, fast and reliable utility set and subroutine library for creating and reading constant databases. The database structure is tuned for fast reading:

- Successful lookups take normally just two disk accesses. - Unsuccessful lookups take only one disk access. - Small disk space and memory size requirements; a database uses 2048 bytes for the header and 24 bytes plus size of (key,value) per record. - Maximum database size is 4GB; individual record size is not otherwise limited. - Portable file format. - Fast creation of new databases. - No locking, updates are atomical.
