+Current status
+--------------
+The schematics are successfully converted.
+
+All the copper layers convert reasonably well. The challenges are mostly
+around filled polygons on the various layers. A python script (fix-pcb.py)
+modifies parameters to get a fairly close result.
+
+Importing WRL files (3D models) required some hacking of the altium2kicad
+tool that I haven't been able to work on upstreaming yet.
+
+Another hack that has not been upstreamed is loading more of the source
+files, IIRC to get all component footprints properly converted.
+
+
+Issues
+------
+Two layers (Altium Gerber files CrypTech.G1 and CrypTech.G2) have fills
+that I have not been able to reproduce. I targeted not missing any copper,
+accepting that the KiCAD gerber fills reach more places, so add some copper
+on those layers.
+
+Drill hole sizes have not been checked. KiCAD seems to add ~0.85 mil more
+clearance around vias. This needs to be double checked but I'm hoping that
+we can just tolerate that.
