Match curves (and merge)

Hi,

I can not find a command in rhinscripsyntax / Rhino module, which equals the 'match' command in Rhino. This command changes the end of one curve to match the curvature (or position or tangency) of the end of another curve and optionally merges the curves.

Is it not (yet???) included in the sdk?

Does anybody know a workaround?

Thanks in advance!
