 suitesparse is a collection of libraries for computations involving sparse
 matrices.  The package includes the following libraries:
 
-  AMD         approximate minimum degree ordering
-  BTF         permutation to block triangular form (beta)
-  CAMD        constrained approximate minimum degree ordering
-  COLAMD      column approximate minimum degree ordering
-  CCOLAMD     constrained column approximate minimum degree ordering
-  CHOLMOD     sparse Cholesky factorization
-  CXSparse    CSparse extended: complex matrix, int and long int support
-  KLU         sparse LU factorization, primarily for circuit simulation
-  LDL         a simple LDL' factorization
-  SQPR        a multithread, multifrontal, rank-revealing sparse QR
-              factorization method
-  UMFPACK     sparse LU factorization
-  UFconfig    configuration file for all the above packages.

 NOTES:
 
+* To build octave with SuiteSparse 4.x you'll need to add a second library
+to the octave's configure option --with-umfpack:
+
+    --with-umfpack="-lumfpack -lsuitesparseconfig"
+
 * CHOLMOD can also be compiled to use the METIS library, but it is not
-  used here because its licensing terms exclude it from Octave.

 * CXSparse is a superset of CSparse, and the two share common header
-  names, so it does not make sense to build both. CXSparse is built
-  by default.
