 cdb is a fast, reliable, lightweight 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

-Note for developers:  packages that need to read cdb files should
-incorporate the necessary portions of the cdb library rather than
-relying on an external cdb library. (See WWW)
