-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.

-+# SYNOPSIS
-+#
-+#   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.

-# 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

-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.
