NAME
       CPANPLUS::Backend::RV - return value objects for
       multi-module calls to CPANPLUS::Backend

SYNOPSIS
           ### create a CPANPLUS::Backend::RV object
           $backend_rv     = CPANPLUS::Backend::RV->new(
                                       ok          => $boolean,
                                       args        => $args,
                                       rv          => $return_value
                                       function    => $calling_function );

           ### if you have a CPANPLUS::Backend::RV object
           $passed_args    = $backend_rv->args;    # args passed to function
           $ok             = $backend_rv->ok;      # boolean indication overall
                                                   # result of the call
           $function       = $backend_rv->fucntion # name of the calling
                                                   # function
           $rv             = $backend_rv->rv       # the actual return value
                                                   # of the calling function

DESCRIPTION
       This module provides return value objects for multi-module
       calls to CPANPLUS::Backend. In boolean context, it returns
       the status of the overall result (ie, the same as the "ok"
       method would).

METHODS
   new( ok => BOOL, args => DATA, rv => DATA, [function =>
       $method_name] )
       Creates a new CPANPLUS::Backend::RV object from the data
       provided.  This method should only be called by
       CPANPLUS::Backend functions.  The accessors may be used by
       users inspecting an RV object.

       All the argument names can be used as accessors later to
       retrieve the data.

       Arguments:

       ok  Boolean indicating overall success

       args
           The arguments provided to the function that returned
           this rv object.  Useful to inspect later to see what
           was actually passed to the function in case of an
           error.

       rv  An arbitrary data structure that has the detailed
           return values of each of your multi-module calls.

       function
           The name of the function that created this rv object.
           Can be explicitly passed. If not, "new()" will try to
