GNU recutils introductory talk video
The FSCONS people recently uploaded the video recordings of the talks which were done in the last edition. Among these there is a GNU recutils talk which introduces the concepts implemented by recutils and provides an overview of the rec format and the utilities.
As a novelty, this is the first recording of a recutils introductory talk where you can actually read what is written in the slides :)
Also make sure to take a look to the other videos! Lots of interesting stuff, as is usual in the FSCONS conference.
