  PP-ind is a repository of audio-video-recordings of industrial pair
programming sessions. Since 2007, our research group has collected data in 13
companies. A total of 57 developers worked together (mostly in groups of two,
but also three or four) in 67 sessions with a mean length of 1:35 hours. In
this report, we describe how we collected the data and provide summaries and
characterizations of the sessions.
