	11	@class wxExtHelpController
	12
	13	This class implements help via an external browser.
	14	It requires the name of a directory containing the documentation
	15	and a file mapping numerical Section numbers to relative URLS.
	16
	17	The map file contains two or three fields per line:
	18	numeric_id relative_URL [; comment/documentation]
	19
	20	The numeric_id is the id used to look up the entry in
	21	DisplaySection()/DisplayBlock(). The relative_URL is a filename of
	22	an html file, relative to the help directory. The optional
	23	comment/documentation field (after a ';') is used for keyword
	24	searches, so some meaningful text here does not hurt.
	25	If the documentation itself contains a ';', only the part before
	26	that will be displayed in the listbox, but all of it used for search.
	27
	28	Lines starting with ';' will be ignored.
