+#
+# SYNOPSIS
+#
+# ACX_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 ACX_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.
+#
+# This macro requires autoconf 2.50 or later.
