It is written in assembly and C, and is free software licensed under the LGPL. It is ported to i386 and ppc64 Linux at present, and currently supports playback of about 34 system calls, which is enough to replay the interesting paths of some server applications and to replay simple dynamically-linked applications in their entirety.
