DDG 2020-02-01: dgw::hyperhelp is a hypertext help system using a Wiki/Markdown like markup language, based on A Hypertext Help System which was cleaned up, extended and documented - HTML - manual links see below. Here an example help page for explaining the hyperhelp markup https://chiselapp.com/user/dgroth/repository/tclcode/doc/tip/dgw/help.txt
The help browser system displays a nice table of contents table in a ttk::treeview widget, offers index, search facilities and sophisticated keyboard navigation.
