  22 /**
  23    This class implements help via wxHTML.
  24    It requires the name of a directory containing the documentation
  25    and a file mapping numerical Section numbers to relative URLS.
  26
  27    The map file contains two or three fields per line:
  28    numeric_id  relative_URL  [; comment/documentation]
  29
  30    The numeric_id is the id used to look up the entry in
  31    DisplaySection()/DisplayBlock(). The relative_URL is a filename of
  32    an html file, relative to the help directory. The optional
  33    comment/documentation field (after a ';') is used for keyword
  34    searches, so some meaningful text here does not hurt.
  35    If the documentation itself contains a ';', only the part before
  36    that will be displayed in the listbox, but all of it used for search.
  37
  38    Lines starting with ';' will be ignored.
