About context-sensitive help

The help system provides a simple mechanism for associating windows and other widgets with help text files.

The help system uses the following abstractions:

widget sum

A unique symbolic tag generated by the help system that is used to associate help with a window or widget. (This sum is based on the full widget name, which can be quite long and identifies its location in the widget tree).

widget tree

The hierarchical arrangement of widget sums of a SCO Visual Tcl application.

hook file

A database file that associates widget sums with text files.

help node

A help topic file associated with one or more widget sums.

help book

A directory that contains all the help files for a manager.
