nl @synopsis ACX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl This macro looks for a library that implements the BLAS
dnl linear-algebra interface (see http://www.netlib.org/blas/).
dnl On success, it sets the BLAS_LIBS output variable to
dnl hold the requisite library linkages.
dnl
dnl To link with BLAS, you should link with:
dnl
dnl $BLAS_LIBS $LIBS $FLIBS
dnl
dnl in that order. FLIBS is the output variable of the
dnl AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS),
dnl and is sometimes necessary in order to link with F77 libraries.
dnl Users will also need to use AC_F77_DUMMY_MAIN (see the autoconf
dnl manual), for the same reason.
dnl
dnl Many libraries are searched for, from ATLAS to CXML to ESSL.
dnl The user may also use --with-blas=<lib> in order to use some
dnl specific BLAS library <lib>. In order to link successfully,
dnl however, be aware that you will probably need to use the same
dnl Fortran compiler (which can be set via the F77 env. var.) as
dnl was used to compile the BLAS library.
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a BLAS
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
dnl the default action will define HAVE_BLAS.
dnl
dnl This macro requires autoconf 2.50 or later.
