! !ARGUMENTS:
    type(ESMF_RouteHandle), intent(inout)          :: routehandle
type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below

! !STATUS:
! \begin{itemize}
! \item\apiStatusCompatibleVersion{5.2.0r}
! \item\apiStatusModifiedSinceVersion{5.2.0r}
! \begin{description}
! \item[8.0.0] Added argument {\tt noGarbage}.
!   The argument provides a mechanism to override the default garbage collection
!   mechanism when destroying an ESMF object.
! \end{description}
! \end{itemize}
!
! !DESCRIPTION:
!   Release resources associated with an ArrayBundle sparse matrix multiplication. 
!   After this call {\tt routehandle} becomes invalid.
!
!   \begin{description}
!   \item [routehandle]
!     Handle to the precomputed Route.
!   \item[{[noGarbage]}]
!     If set to {\tt .TRUE.} the object will be fully destroyed and removed
!     from the ESMF garbage collection system. Note however that under this 
!     condition ESMF cannot protect against accessing the destroyed object 
!     through dangling aliases -- a situation which may lead to hard to debug 
!     application crashes.
! 
!     It is generally recommended to leave the {\tt noGarbage} argument
!     set to {\tt .FALSE.} (the default), and to take advantage of the ESMF 
!     garbage collection system which will prevent problems with dangling
!     aliases or incorrect sequences of destroy calls. However this level of
!     support requires that a small remnant of the object is kept in memory
!     past the destroy call. This can lead to an unexpected increase in memory
!     consumption over the course of execution in applications that use 
!     temporary ESMF objects. For situations where the repeated creation and 
!     destruction of temporary objects leads to memory issues, it is 
!     recommended to call with {\tt noGarbage} set to {\tt .TRUE.}, fully 
!     removing the entire temporary object from memory.
!   \item [{[rc]}]
!     Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!   \end{description}
