+SuiteSparseQR is an implementation of the multifrontal sparse QR
+factorization method. Parallelism is exploited both in the BLAS and
+across different frontal matrices using Intel's Threading Building Blocks,
+a shared-memory programming model for modern multicore
+architectures. It can obtain a substantial fraction of the
+theoretical peak performance of a multicore computer.
+
+This package is part of SuiteSparse.

++# SYNOPSIS
++#
++# AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#
++# DESCRIPTION
++#
++# This macro looks for a library that implements the BLAS linear-algebra
++# interface (see http://www.netlib.org/blas/). On success, it sets the
++# BLAS_LIBS output variable to hold the requisite library linkages.
++#
++# To link with BLAS, you should link with:
++#
++# $BLAS_LIBS $LIBS $FLIBS
++#
++# in that order. FLIBS is the output variable of the
++# AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
++# sometimes necessary in order to link with F77 libraries. Users will also
++# need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
++# reason.
++#
++# Many libraries are searched for, from ATLAS to CXML to ESSL. The user
++# may also use --with-blas=<lib> in order to use some specific BLAS
++# library <lib>. In order to link successfully, however, be aware that you
++# will probably need to use the same Fortran compiler (which can be set
++# via the F77 env. var.) as was used to compile the BLAS library.
++#
++# ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is
++# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
++# not found. If ACTION-IF-FOUND is not specified, the default action will
++# define HAVE_BLAS.

++# AX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#
++# DESCRIPTION
++#
++# This macro looks for a library that implements the LAPACK linear-algebra
++# interface (see http://www.netlib.org/lapack/). On success, it sets the
++# LAPACK_LIBS output variable to hold the requisite library linkages.
++#
++# To link with LAPACK, you should link with:
++#
++# $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
++#
++# in that order. BLAS_LIBS is the output variable of the AX_BLAS macro,
++# called automatically. FLIBS is the output variable of the
++# AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
++# sometimes necessary in order to link with F77 libraries. Users will also
++# need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
++# reason.
++#
++# The user may also use --with-lapack=<lib> in order to use some specific
++# LAPACK library <lib>. In order to link successfully, however, be aware
++# that you will probably need to use the same Fortran compiler (which can
++# be set via the F77 env. var.) as was used to compile the LAPACK and BLAS
++# libraries.
++#
++# ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library
++# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
++# is not found. If ACTION-IF-FOUND is not specified, the default action
++# will define HAVE_LAPACK.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+spqr: SuiteSparseQR (sparse matrix factoring routines)
+spqr:
+spqr: SuiteSparseQR is an implementation of the multifrontal sparse QR
+spqr: factorization method. Parallelism is exploited both in the BLAS
+spqr: and across different frontal matrices using Intel's Threading
+spqr: Building Blocks, a shared-memory programming model for modern
+spqr: multicore architectures. It can obtain a substantial fraction of
+spqr: the theoretical peak performance of a multicore computer.
