pocketing program

I have written a pocketing program using g-codes, it pockets triangles, rectangles, trapezoids and some unusual shapes. the attachment has a screendump of eight different ones.  The program is available as a .ngc file and runs on linuxcnc/axis version 2.6.13 on ubuntu 12.04 LTS 32 bit (using the rtai kernel to operate a Taigtool mill through a xylotec controller.)  I would like to donate this program to the site if there's any interest)  my email address is This email address is being protected from spambots.

the program  is 580 lines long and includes 112 lines of sample polygons. it uses "o" codes a lot.
