Texinfo in general is also better for something longer than a few "pages" since it is meant for actual manuals, with content lists, indexes, search, hyperlinks, chapters, etc instead of the text vomit you get with with a manpage. Similar to Windows CHM (for which there are cross platform tools to create and view - e.g. Free Pascal and Lazarus have their own CHM generator and viewer) and other similar documentation formats that provide some form of organization and metadata.
