+
+/*  Purpose */
+/*  ======= */
+
+/*  This routine is deprecated and has been replaced by routine DGGES. */
+
+/*  DGEGS computes the eigenvalues, real Schur form, and, optionally, */
+/*  left and or/right Schur vectors of a real matrix pair (A,B). */
+/*  Given two square matrices A and B, the generalized real Schur */
+/*  factorization has the form */
+
+/*    A = Q*S*Z**T,  B = Q*T*Z**T */
+
+/*  where Q and Z are orthogonal matrices, T is upper triangular, and S */
+/*  is an upper quasi-triangular matrix with 1-by-1 and 2-by-2 diagonal */
+/*  blocks, the 2-by-2 blocks corresponding to complex conjugate pairs */
+/*  of eigenvalues of (A,B).  The columns of Q are the left Schur vectors */
+/*  and the columns of Z are the right Schur vectors. */
+
+/*  If only the eigenvalues of (A,B) are needed, the driver routine */
+/*  DGEGV should be used instead.  See DGEGV for a description of the */
+/*  eigenvalues of the generalized nonsymmetric eigenvalue problem */
+/*  (GNEP). */
+
+/*  Arguments */
