NAME
     sdr-launch - Session Directory Client Launcher

SYNOPSIS
     /var/netscape/communicator/sdr-launch

DESCRIPTION
     sdr-launch is a HTTP helper application that is launched on the client
     system through the use of the .sdr mime typeextension. This application
     parses the session directory announcement sent by the Web Server and
     after consulting the transformations file (mbone-fmt.txt) launches the
     appropriate media tool for audio, video, whiteboard announcements.

   Operation
     The format of the mbone-fmt.txt file is as follows:
     Each line consists a announcement media`format' field. Each one of these
     fields can be followed by 3 other fields specifying (1) name of the
     application to launch for playing that format, (2) full path of the
     application, and (3) the complete set of command line options in the
     application specific syntax for that application.
     There is also a line each provided for the `default-audio', `default-
     radio', `default-video', and `default-wb'. These `default' entries are
     used in the transformation if either the specified media format is not
     found in the file or is empty.

     Currently the following attributes are available for use in the
     application command line options.
          ttl            Time to Live value of the announcement
          format         media format
          multicast      Multicast Address of the announcement
          address
          port           Port number of the announcement
          multicast ID   Multicast ID of the announcement, this is
                         sometimes used by some of the applications
     Each one of these options need to be prefixed with a `+', this tells the
     launcher that it needs to stuff actual values for them.
