++##### http://autoconf-archive.cryp.to/acx_blas.html
++#
++# 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.
