+ #   ssi_with_retries - Does the server side include of a resource.
+ #                      if the ssi call returns an error we'll retry it up to
+ #                      the number of times requested by the caller.
+ #                      If we still have a proble, no text is appended to the
+ #                      output and we set some global variables.
+ #                      to indicate to the caller an SSI error occurred.
+ #                      All of this is supposed to deal with the issues described
+ #                      in LonCAPA BZ 5631 see:
+ #                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
+ #                      by informing the user that this happened.
+ #
+ # Parameters:
+ #   resource   - The resource to include.  This is passed directly, without
+ #                interpretation to lonnet::ssi.
+ #   form       - The form hash parameters that guide the interpretation of the resource
+ #
+ #   retries    - Number of retries allowed before giving up completely.
+ # Returns:
+ #   On success, returns the rendered resource identified by the resource parameter.
+ # Side Effects:
+ #   The following global variables can be set:
+ #    ssi_error                - If an unrecoverable error occurred this becomes true.
+ #                               It is up to the caller to initialize this to false
+ #                               if desired.
+ #    ssi_last_error_resource  - If an unrecoverable error occurred, this is the value
+ #                               of the resource that could not be rendered by the ssi
+ #                               call.
