+dxfgrabber branch notes
+=======================
 
-LasaurApp
+This branch replaces the lasersaur dxf reader with a parser driving
+dxfgrabber.   All new work added by jet is under the existing
+lasersaur licensing.  This work is done on jet's personal time,
+not supported by any commercial entities, and donations are always welcome.
+
+You'll need to install the latest dxfgrabber from console:
+
+root@laserdev:~/LasaurApp# pip install dxfgrabber
+
+Changes:
+
+- dxf line colors from entity or entity layer
+- dxf units converted to mm
+- flip dxf files on the Y axis by default
+
+In Testing:
+- flip dxf files on the X axis by default
+
+TODO list:
+- fix circle/arc generation?  Make test file with holes from 1mm to
+  25mm for tests.
+- TEXT YES TEXT I'M WORKING ON THAT DILUTE! DILUTE! OK!
+- more dxf entities
+- remapping/reducing dxf color sets down to a set of 0..7
+  (which will probably change when we start rasterizing)

 When running on the Driveboard people can start using the 'saur' directly from their laptop without having to setup any software or drivers. This is done this way because we imagine laser cutters being shared in shops. We see people controlling laser cutters from their laptops and not wanting to go through annoying setup processes. Besides this, html-based GUIs are just awesome :)
