General camera and CHDK port information
****************************************
Default alt button is PLAY. VIDEO and WIFI may also be used

Subject distance (focus) override is available only when MF or AF lock is set

Only simple_movie_status is implemented, so features or scripts that rely on
direct access to the movie_status variable do not work

When running a script ~600k of RAM is available to CHDK.

This camera has an adjustable aperture and does not have an ND filter.

HDMI hotplug, analog AV detect, and battery temperature A/D are supported
as alternate remote inputs.
