GNU Recutils

GNU Recutils is a set of tools and libraries to access human-editable, plain text databases called recfiles. The data is stored as a sequence of records, each record containing an arbitrary number of named fields. The picture below shows a sample database containing information about GNU packages, along with the main features provided by Recutils.

  • A video with a talk introducing the program can be found here.
  • An older video, which was recorded just before releasing the first version, can be downloaded from here
  • Some of the people involved in GNU Recutils hang out in the #recutils channel on the irc.freenode.net IRC network. You are more than welcome to join.
