Documentation

This class implements help via an external browser. It requires the name of a directory containing the documentation and a file mapping numerical Section numbers to relative URLS.

The map file contains two or three fields per line: numeric_id relative_URL [; comment/documentation]

The numeric_id is the id used to look up the entry in DisplaySection()/DisplayBlock(). The relative_URL is a filename of an html file, relative to the help directory. The optional comment/documentation field (after a ';') is used for keyword searches, so some meaningful text here does not hurt.

This class has no child classes.
