GNU dbm database routines (legacy support development files)

 GNU dbm ('gdbm') is a library of database functions that use extendible
 hashing and works similarly to the standard UNIX 'dbm' functions.
 The basic use of 'gdbm' is to store key/data pairs in a data file, thus
 providing a persistent version of the 'dictionary' Abstract Data Type
 ('hash' to perl programmers).
 This package includes development files, required to build old
 programs, that use legacy 'dbm' interface. For new programs, please
 use modern interface, provided by libgdbm6 and libgdbm-dev.
