! !DESCRIPTION:
!   Set up a MinThreads vmplan.
!
!   The arguments are:
!   \begin{description}
!   \item[vmplan] 
!        VMPlan
!   \item[vm] 
!        VM
!   \item[{[max]}] 
!        Maximum number of cores per thread
!   \item[{[pref_intra_process]}] 
!        Intra process communication preference
!   \item[{[pref_intra_ssi]}] 
!        Intra SSI communication preference
!   \item[{[pref_inter_ssi]}] 
!        Inter process communication preference
!   \item[npetlist] 
!        Number of PETs in petlist
!   \item[petlist] 
!        List of PETs that the parent VM will provide to the child VM
!   \item[{[forceEachChildPetOwnPthread]}] 
!        For {\tt .true.}, force each child PET to execute in its own Pthread.
!        By default, {\tt .false.}, single PETs spawned from a parent PET
!        execute in the same thread (or MPI process) as the parent PET. Multiple
!        child PETs spawned by the same parent PET always execute as their own
!        Pthreads.
!   \item[{[rc]}] 
!        Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!   \end{description}
