++# ===========================================================================

++# ===========================================================================
++#
++# 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.

+# 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.
