  27 /**
  28    This class implements help via an external browser.
  29    It requires the name of a directory containing the documentation
  30    and a file mapping numerical Section numbers to relative URLS.
  31
  32    The map file contains two or three fields per line:
  33    numeric_id  relative_URL  [; comment/documentation]
  34
  35    The numeric_id is the id used to look up the entry in
  36    DisplaySection()/DisplayBlock(). The relative_URL is a filename of
  37    an html file, relative to the help directory. The optional
  38    comment/documentation field (after a ';') is used for keyword
  39    searches, so some meaningful text here does not hurt.
  40    If the documentation itself contains a ';', only the part before
  41    that will be displayed in the listbox, but all of it used for search.
  42
  43    Lines starting with ';' will be ignored.
