54This class implements help via an external browser.
55It requires the name of a directory containing the documentation
56and a file mapping numerical Section numbers to relative URLS.<P>The map file contains two or three fields per line:
57numeric_id relative_URL [; comment/documentation]<P>The numeric_id is the id used to look up the entry in
58DisplaySection()/DisplayBlock(). The relative_URL is a filename of
59an html file, relative to the help directory. The optional
60comment/documentation field (after a ';') is used for keyword
61searches, so some meaningful text here does not hurt.
62If the documentation itself contains a ';', only the part before
63that will be displayed in the listbox, but all of it used for search.<P>Lines starting with ';' will be ignored.<P>This confuses DOC++, so I leave it out for now:
