/**
|
|
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.
|
|
If the documentation itself contains a ';', only the part before
|
|
that will be displayed in the listbox, but all of it used for search.
|
|
|
|
Lines starting with ';' will be ignored.
