- 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.
