Yes. Here's the man page output:

  http://ana-3.lcs.mit.edu/~jnc/tech/unix/help/b.out.lpt

(I don't have the source for that, alas.) It's basically just a.out with
32-bit fields instead of 16-bit. I have a .h file for the format too, if
anyone has any interest in it. It's all part of the MIT 68K workbench that
used PCC (the source for all of which I do have).
