dnl @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.

\`configure' configures this package to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

EOF

  cat <<EOF
Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
  --infodir=DIR          info documentation [PREFIX/info]
  --mandir=DIR           man documentation [PREFIX/man]

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-blas=<lib>       use BLAS library <lib>
  --with-lapack=<lib>     use LAPACK library <lib>

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
              headers in a nonstandard directory <include dir>
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
