If you have the eHelp (RoboHelp) license that permits you to redistribute the appropriate eHelp DLL, you can use Mif2Go to produce WinHelp 2000. You generate WinHelp, then add the eHelp data to the WinHelp project file before you compile; see §7.1.10 . Also, you can generate HTML Help as a precursor to using RoboHelp to generate WebHelp; see §6.1.4 .
If you need something similar to WebHelp or Web Works Help, try generating OmniHelp; see §6.1.5 . Otherwise you would have to roll your own, which you could do with Mif2Go frameset support; see §12.12 . OmniHelp provides a simpler and faster solution.
If you need Microsoft Help 2, you can generate HTML Help with Mif2Go and then use FAR to convert the resulting .chm file to .hxs, H2Reg to register the Help system, and Ndoc for reference information:
