It is the top utility in this page of linuxcnc code generators: <http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G- Code_Generators#Counterbore_Software> I looked at it, just enough to understand I haven't learned a thing in 2 years of lurking on this list. I see Big John has a bug note, and its possible this might be related. You can get it at the upper link, or there is a copy on my pages, under Genes-os9-stf/LCNC directory.
