+# 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.

+# DESCRIPTION
+#
+# This macro looks for a library that implements the LAPACK linear-algebra

+#
+# 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
