12.4.2 Supplying path information for contents and index links
If your HTML files will not be in the same directory with toc.xml and idx.xml, links from these files must include a path.
To supply a path for contents and index links, and also for <context> elements (see §12.7 Setting up CSH for Eclipse Help):
; TocIdxFilePrefix = prefix to insert at start of file URLs, when
; html files are placed in a subdirectory under the toc and idx
TocIdxFilePrefix = path/to/htmlfiles
The path specified by TocIdxFilePrefix is relative to the directory where toc.xml and idx.xml are located, and must designate a subdirectory under that directory.
