- and a file mapping numerical Section numbers to relative URLS.

+// headers
+// ----------------------------------------------------------------------------
- The map file contains two or three fields per line:
- numeric_id relative_URL [; comment/documentation]
+#include "wx/helpbase.h"
- 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.
