longDescription = ''
GNU dbm (or GDBM, for short) is a library of database functions that
use extensible hashing and work similar to the standard UNIX dbm.
These routines are provided to a programmer needing to create and
manipulate a hashed database.
The basic use of GDBM is to store key/data pairs in a data file.
Each key must be unique and each key is paired with only one data
item.
The library provides primitives for storing key/data pairs,
searching and retrieving the data by its key and deleting a key
along with its data. It also support sequential iteration over all
key/data pairs in a database.
For compatibility with programs using old UNIX dbm function, the
package also provides traditional dbm and ndbm interfaces.
