/* A 'picture' is a single standalone picture.
 * A 'clip' is an autoshoot clip.
 * A 'frame' is a single a picture out of a clip.
 * An 'entry' corresponds to a line listed in the camera's configuration data,
 * part of which is a rudimentary allocation table (the 'catalog'). 
 * An entry, therefore, may be either a picture or a clip. 
 * We reserve the word 'file' for the user fetchable file,
 * that is, a picture or a frame.
