  21  * NOTES:
  22  *  Winebrowser is a winelib application that will start the appropriate
  23  *  native browser or mail client for a wine installation that lacks a
  24  *  windows browser/mail client. For example, you will be able to open
  25  *  urls via native mozilla if no browser has yet been installed in wine.
  26  *
  27  *  The application to launch is chosen from a default set or, if set,
  28  *  taken from a registry key.
  29  *
  30  *  The argument may be a regular Windows file name, a file URL, an
  31  *  URL or a mailto URL. In the first three cases the argument
  32  *  will be fed to a web browser. In the last case the argument is fed
  33  *  to a mail client. A mailto URL is composed as follows:
  34  *
  35  *   mailto:[E-MAIL]?subject=[TOPIC]&cc=[E-MAIL]&bcc=[E-MAIL]&body=[TEXT]
