With Hypermake (earlier version "MakeIPF"), you can easily create HTML files or IBM IPF files, Winhelp and Microsoft HTML-Help files. Instead of editing the HTML, IPF or RTF files directly, you enter a more simple ASCII source text.
Links are created automatically; windows of different headings levels can be shown simultaneusly (frames) with only one command; at the end of a chapter,
links to subchapters are created automatically and a lot of more.
