+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.
+
+This requires blas and lapack.
+
+suitesparse is an optional dependency for the octave package.
+
+NOTES:
+
+* 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.
+
+* SlackBuilds.org also has all the parts of this suite as individual
+  builds DO NOT try and install the individual parts and the suite pick
+  one or the other.

+
+#------------------------------------------------------------------------------
+# Generic configuration
+#------------------------------------------------------------------------------
+
+# C compiler and compiler flags:  These will normally not give you optimal
+# performance.  You should select the optimization parameters that are best
+# for your system.  On Linux, use "CFLAGS = -O3 -fexceptions" for example.
+CC = cc
+# CFLAGS = -O   (for example; see below for details)
+
+# C++ compiler (also uses CFLAGS)
+CPLUSPLUS = g++
+
+# ranlib, and ar, for generating libraries
+RANLIB = ranlib
+AR = ar cr
+
+# delete and rename a file
+RM = rm -f
+MV = mv -f
+
+# Fortran compiler (not normally required)
+F77 = gfortran
+F77FLAGS = -O
+F77LIB =
+
+# C and Fortran libraries
+LIB = -lm
+
+# For compiling MATLAB mexFunctions (MATLAB 7.5 or later)
+MEX = mex -O -largeArrayDims -lmwlapack -lmwblas
+
+# For compiling MATLAB mexFunctions (MATLAB 7.3 and 7.4)
+# MEX = mex -O -largeArrayDims -lmwlapack
+
+# For MATLAB 7.2 or earlier, you must use one of these options:
+# MEX = mex -O -lmwlapack
+# MEX = mex -O
+
+# Which version of MAKE you are using (default is "make")
+# MAKE = make
+# MAKE = gmake
+
+#------------------------------------------------------------------------------
+# BLAS and LAPACK configuration:
+#------------------------------------------------------------------------------
+
+# UMFPACK and CHOLMOD both require the BLAS.  CHOLMOD also requires LAPACK.
+# See Kazushige Goto's BLAS at http://www.cs.utexas.edu/users/flame/goto/ or
+# http://www.tacc.utexas.edu/~kgoto/ for the best BLAS to use with CHOLMOD.
+# LAPACK is at http://www.netlib.org/lapack/ .  You can use the standard
+# Fortran LAPACK along with Goto's BLAS to obtain very good performance.
+# CHOLMOD gets a peak numeric factorization rate of 3.6 Gflops on a 3.2 GHz
+# Pentium 4 (512K cache, 4GB main memory) with the Goto BLAS, and 6 Gflops
+# on a 2.5Ghz dual-core AMD Opteron.
+
+# These settings will probably not work, since there is no fixed convention for
+# naming the BLAS and LAPACK library (*.a or *.so) files.
+
+# Using the Goto BLAS:
+# BLAS = -lgoto -lgfortran -lgfortranbegin -lg2c
+
+# This is probably slow ... it might connect to the Standard Reference BLAS:
+BLAS = -lblas -lgfortran -lgfortranbegin 
+LAPACK = -llapack
+
+# Using non-optimized versions:
+# BLAS = -lblas_plain -lgfortran -lgfortranbegin -lg2c
+# LAPACK = -llapack_plain
+
+# The BLAS might not contain xerbla, an error-handling routine for LAPACK and
+# the BLAS.  Also, the standard xerbla requires the Fortran I/O library, and
+# stops the application program if an error occurs.  A C version of xerbla
+# distributed with this software (UFconfig/xerbla/libcerbla.a) includes a
+# Fortran-callable xerbla routine that prints nothing and does not stop the
+# application program.  This is optional.
+# XERBLA = ../../UFconfig/xerbla/libcerbla.a 
+
+# If you wish to use the XERBLA in LAPACK and/or the BLAS instead,
+# use this option:
+XERBLA = 
+
+# If you wish to use the Fortran UFconfig/xerbla/xerbla.f instead, use this:
+# XERBLA = ../../UFconfig/xerbla/libxerbla.a 
+
+#------------------------------------------------------------------------------
+# METIS, optionally used by CHOLMOD
+#------------------------------------------------------------------------------
+
+# If you do not have METIS, or do not wish to use it in CHOLMOD, you must
+# compile CHOLMOD with the -DNPARTITION flag.  You must also use the
+# "METIS =" option, below.
+
+# The path is relative to where it is used, in CHOLMOD/Lib, CHOLMOD/MATLAB, etc.
+# You may wish to use an absolute path.  METIS is optional.  Compile
+# CHOLMOD with -DNPARTITION if you do not wish to use METIS.
+#METIS_PATH = ../../metis-4.0
+#METIS = ../../metis-4.0/libmetis.a
+
+# If you use CHOLMOD_CONFIG = -DNPARTITION then you must use the following
+# options:
+METIS_PATH =
+METIS =

+#------------------------------------------------------------------------------
+# UMFPACK configuration:
+#------------------------------------------------------------------------------
+
+# Configuration flags for UMFPACK.  See UMFPACK/Source/umf_config.h for details.
+#
+# -DNBLAS	do not use the BLAS.  UMFPACK will be very slow.
+# -D'LONGBLAS=long' or -DLONGBLAS='long long' defines the integers used by
+#  		LAPACK and the BLAS (defaults to 'int')
+# -DNSUNPERF	do not use the Sun Perf. Library (default is use it on Solaris)
