General help facility that can be added to Motif programs
Description:
Once NXHelp has been added to a program, the program can activate the facility at any time. Once activated the user will see a window displaying a list of available help topics. When the user selects a topic, the appropriate text is then displayed. To use NXHelp within a program, you will first create a text file containing the help information that you wish to display to the user and then call an NXhelp initialisation function.
