My remap is built on top of a previous but unfinished experimental branch:
https://github.com/LinuxCNC/linuxcnc/tree/BenPotter/G71

I really want us to stop re-doing this. There have been several
attempts made, and none committed.

My Type-2 version was done in Python mainly because I thought of what
I believed to be a neat algorithm one night, and wanted to try it out.
I consider my only real contribution useful to LinuxCNC to be the manual pages.

I just followed an existing implementation (the one above) and used
all the same letters. I had assumed that it was built on a standard
from a commercial control, possibly Okuma?

I guess that if the letters are different then the images from my
manual pages are not re-usable either.

Does it use the front angle and back angle data? (I could check the
code, of course, but I have just got back from 2 weeks holiday and I
am working through a huge backlog of email and forum posts)

True, but I chose to generalise my implementation as it is easier to
do that now than later. I can imagine that a multi-slide lathe might
want to use YZ and possibly UZ.
