This backend can be used by portal implementations that
      need to choose an application from a list of applications.

This documentation describes version 2 of this interface.

The following results get returned via the @results vardict:

              A token that can be used to activate the chosen application. If
              the application selection has involved user interaction, a new
              token should be generated by the portal implementation.
              Otherwise, this token may be the same as the one passed in
              @options.
