You want libtap(3), which outputs the necessary format.  I wrote it, 
then got caught up with other things, and now Rusty Russel 
(rusty at rustcorp.com.au, copied) maintains it.

There's a repo at http://ccan.ozlabs.org/repo/ccan_tools/libtap/ -- IIRC 
there's also a port (which probably needs updating).
