Subject: vmd-l: helix axes

This must be simple but I haven't yet found it (I'm still in the early
stages of trying to learn scripting): is there a way to determine the
central axis of an alpha helix, and to calculate the dihedral angle
between two such axes? If this is explained somewhere or there's a plugin,
please direct me. Thanks very much.
