     It's not very complicated.  Here's part of one.

     The first part describes the "tools", the drills being used
(you have to provide a tool list separately), and then we see the holes
being specified, with the tool number ("T01") and the hole locations
"X029Y018".  That's the general idea.

     Most CAD systems for laying out printed circuit boards will produce
a drill file.
