   *> Sort the numbers in D in increasing order (if ID = 'I') or

   *>          D is DOUBLE PRECISION array, dimension (N)
   *>          On entry, the array to be sorted.

   *>          (D(1) >= ... >= D(N) ), depending on ID.

   *> \verbatim
   *>          INFO is INTEGER
   *>          = 0:  successful exit
