-* Definition:
-* ===========
-*
-* SUBROUTINE DLASRT( ID, N, D, INFO )
-*
-* .. Scalar Arguments ..
-* CHARACTER ID
-* INTEGER INFO, N
-* ..
-* .. Array Arguments ..
-* DOUBLE PRECISION D( * )
-* ..
-*
-*
-*> \par Purpose:
-* =============
-*>
-*> \verbatim
-*>
-*> Sort the numbers in D in increasing order (if ID = 'I') or
-*> in decreasing order (if ID = 'D' ).
-*>
-*> Use Quick Sort, reverting to Insertion sort on arrays of
-*> size <= 20. Dimension of STACK limits N to about 2**32.
-*> \endverbatim
-*
-* Arguments:
-* ==========
-*
-*> \param[in] ID
-*> \verbatim
-*> ID is CHARACTER*1
-*> = 'I': sort D in increasing order;
-*> = 'D': sort D in decreasing order.
-*> \endverbatim
-*>
-*> \param[in] N
-*> \verbatim
-*> N is INTEGER
-*> The length of the array D.
-*> \endverbatim
-*>
-*> \param[in,out] D
-*> \verbatim
-*> D is DOUBLE PRECISION array, dimension (N)
-*> On entry, the array to be sorted.
-*> On exit, D has been sorted into increasing order
-*> (D(1) <= ... <= D(N) ) or into decreasing order
-*> (D(1) >= ... >= D(N) ), depending on ID.
-*> \endverbatim
-*>
-*> \param[out] INFO
-*> \verbatim
-*> INFO is INTEGER
-*> = 0: successful exit
-*> < 0: if INFO = -i, the i-th argument had an illegal value
-*> \endverbatim
