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.
27 * The application to launch is chosen from a default set or, if set,
28 * taken from a registry key.
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:
35 * mailto:[E-MAIL]?subject=[TOPIC]&cc=[E-MAIL]&bcc=[E-MAIL]&body=[TEXT]
