                          About GNU recutils

GNU recutils is a set of tools and libraries to access human-editable,
text-based databases called recfiles.  The data is stored as a
sequence of records, each record containing an arbitrary number of
named fields.  Advanced capabilities usually found in other data
storage systems are supported by GNU recutils: data types, data
integrity (keys, mandatory fields, etc) as well as the ability of
records to refer to other records (sort of foreign keys).  Despite its
simplicity, recfiles can be used to store medium-sized databases.

Please see the GNU recutils homepage for more information:
