+%description
+SuiteSparse is a suite of sparse matrix algorithms.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
+  CSparse             a concise sparse matrix package
+  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
+  SuiteSparse_config  configuration file for all the above packages.
+  RBio                read/write files in Rutherford/Boeing format
