How do I engrave this articulation? a note with a dot and a right angle bracket underneath it?

[Kenneth Wolcott]

Hi;

  c-. and c-> Lilypond articulation engravings I understand, but I
don't understand how to put a dot underneath the note and then a right
angle bracket under the dot.

See attached screen shot.

Thanks,
Ken
