Thanks to Michael's help, I have been able to add a script that will create a lead-in and lead-out for profiles that will use tool diameter compensation. I also added a couple of helper scripts to the repository. It presently only works on closed curves with arcs and lines, which is how I like to design my machined parts anyhow.

You can use OrderCurves to set the direction of the curve. CreateLeadInOut will set the start of the curve to a point on the curve of your choosing (using crv.changeClosedCurveSeam) after you set the lead-in radius and the overlap.
