SDP-ified:
* Changed sample path to reference SDP /p4/common/bin/triggers
location.
* Changed shebang line to use SDP standard python, which includes
P4Python.
* Removed the '$Id:' RCS keywordt ag line, as RCS tags aren't allowed
in the SDP (since SDP scripts live in many Perforce servers).
* Changed file time from text+kx to text+x.
* Updated copyright up thru 2016.
* One minor cosmetic tweak to doc text.
