* NOTES:
* Winebrowser is a winelib application that will start the appropriate
2005-11-24 19:27:41 +01:00
* native browser or mail client for a wine installation that lacks a
* windows browser/mail client. For example, you will be able to open
* urls via native mozilla if no browser has yet been installed in wine.
*
* The application to launch is chosen from a default set or, if set,
* taken from a registry key.
*
2006-02-18 15:50:06 +01:00
* The argument may be a regular Windows file name, a file URL, an
* URL or a mailto URL. In the first three cases the argument
2006-02-18 15:50:06 +01:00
* will be fed to a web browser. In the last case the argument is fed
* to a mail client. A mailto URL is composed as follows:
2005-11-24 19:27:41 +01:00
*
* mailto:[E-MAIL]?subject=[TOPIC]&cc=[E-MAIL]&bcc=[E-MAIL]&body=[TEXT]
