NetHelp system files are freely available as part of the NetHelp software developer's kit (SDK). Developers can use these files to create their own help systems. For documentation on using NetHelp and the NetHelp SDK, go to:

Communicator version 4.5 will include a NetHelp-based help system. Versions
after 4.5 are planned to use a new help display mechanism.
