Thank you! (the missing degree symbol might be a font issue, no?)
fixed https://github.com/jnweiger/inkscape-gears-dev/issues/20
Merge branch 'master' of github.com:jnweiger/inkscape-gears-dev
so that I can push again...
V0.8: Added option to turn the undercut alert into console output.
The information it produces is valuable, but the console is not always visible to endusers.
But the confirming the alert *every time* can be annoying. Thus we allow the user to choose.
Fixed https://github.com/jnweiger/inkscape-gears-dev/issues/19 -- ring gears are now okay.
profile shift added. Fixed https://github.com/jnweiger/inkscape-gears-dev/issues/9
oops, needed to invert undercut.
Negative profile shift help against undercut. This is how the books say.
