+go-cdb is a pure [Go](http://golang.org/) package to read and write cdb ("constant database") files.
+
+The cdb file format is a machine-independent format with the following 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.
