BrowseX now supports fully user definable Mimetypes. There are now definitions for running external programs for viewing postscript files, mp3 sound files, etc. You can change these settings and even define your own handlers for custom mime types using the dialog in Edit/Prefs/Other/Other/Mimetypes. These handlers are used both in browser rendered pages and by the Mailer. If you define a handler that begins with a | (pipe), the filtered output is passed back for rendering as HTML.

In lieu of actual documentation following is a dump of the predefined types provided in the initial release.
