     This presents a GUI for browsing the list of R packages on one or
     more repositories such as CRAN, Omegahat, BioConductor. The
     packages are presented in a tree, grouped by repository. Selecting
     a package named displays its details taken from its DESCRIPTION
     file. One can also click on a button in that page to install that
     package.

 mirrors: a named character vector containing elements of the form
          repository name and URL in which the packages are to be
          found.

    CRAN: the URL identifying the location of the CRAN repository. By
          default, this is taken from the session's options, but one
          can specify a different mirror as one desires.

    pkgs: information about the packages in the mirrors. This can be
          downloaded previously and passed to this function to avoid
          re-fetching the material over the network.

_V_a_l_u_e:

     A list with elements 

  window: the 'GtkWindow' object which gives the display

packages: the package information which can be used in subsequent calls
          via the 'pkgs' argument to avoid having to download the
          details again.
