+# 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.
