creating and reading constant databases

freecdb is a fast, reliable, simple package for creating and reading constant databases. Its database structure provides several features:

 * Fast lookups: A successful lookup in a large database normally takes
   just two disk accesses.  An unsuccessful lookup takes only one.
 * Low overhead: A database uses 2048 bytes, plus 24 bytes per record,
   plus the space for keys and data.
 * No random limits: cdb can handle any database up to 4 gigabytes.
   There are no other restrictions; records don't even have to fit into
   memory.  Databases are stored in a machine-independent format.
 * Fast atomic database replacement: cdbmake can rewrite an entire
   database two orders of magnitude faster than other hashing packages.
 * Fast database dumps: cdbdump prints the contents of a database in
   cdbmake-compatible format.

This package is derived from the cdb package, and uses the original cdb library. See http://cr.yp.to/cdb.html
