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 $FCLIBS
dnl
dnl in that order. FCLIBS is the output variable of the
dnl AC_FC_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS),
dnl and is sometimes necessary in order to link with FC libraries.
dnl Users will also need to use AC_FC_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 FC 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.

dnl @synopsis ACX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl This macro looks for a library that implements the LAPACK
dnl linear-algebra interface (see http://www.netlib.org/lapack/).
dnl On success, it sets the LAPACK_LIBS output variable to
dnl hold the requisite library linkages.
dnl
dnl To link with LAPACK, you should link with:
dnl
dnl $LAPACK_LIBS $BLAS_LIBS $LIBS
dnl
dnl in that order. BLAS_LIBS is the output variable of the ACX_BLAS
dnl macro, called automatically. 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 The user may also use --with-lapack=<lib> in order to use some
dnl specific LAPACK 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 LAPACK and BLAS libraries.
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a LAPACK
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_LAPACK.

# SYNOPSIS
#
# AX_PYTHON_DEVEL([version])
#
# DESCRIPTION
#
# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
# in your configure.ac.
#
# This macro checks for Python and tries to get the include path to
# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
# variables. It also exports $(PYTHON_EXTRA_LIBS) and
# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
#
# You can search for some particular version of Python by passing a
# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
# note that you *have* to pass also an operator along with the version to
# match, and pay special attention to the single quotes surrounding the
# version number. Don't use "PYTHON_VERSION" for this: that environment
# variable is declared as precious and thus reserved for the end-user.
#
# This macro should work for all versions of Python >= 2.1.0. As an end
# user, you can disable the check for the python version by setting the
# PYTHON_NOVERSIONCHECK environment variable to something else than the
# empty string.
#
# If you need to use this macro for an older Python version, please
# contact the authors. We're always open for feedback.

# SYNOPSIS
#
# AX_LIB_HDF5([serial/parallel])
#
# DESCRIPTION
#
# This macro provides tests of the availability of HDF5 library.
#
# The optional macro argument should be either 'serial' or 'parallel'. The
# former only looks for serial HDF5 installations via h5cc. The latter
# only looks for parallel HDF5 installations via h5pcc. If the optional
# argument is omitted, serial installations will be preferred over
# parallel ones.
#
# The macro adds a --with-hdf5 option accepting one of three values:
#
# no - do not check for the HDF5 library.
# yes - do check for HDF5 library in standard locations.
# path - complete path to the HDF5 helper script h5cc or h5pcc.
#
# If HDF5 is successfully found, this macro calls
#
# AC_SUBST(HDF5_VERSION)
# AC_SUBST(HDF5_CC)
# AC_SUBST(HDF5_CFLAGS)
# AC_SUBST(HDF5_CPPFLAGS)
# AC_SUBST(HDF5_LDFLAGS)
# AC_SUBST(HDF5_LIBS)
# AC_SUBST(HDF5_FC)
# AC_SUBST(HDF5_FFLAGS)
# AC_SUBST(HDF5_FLIBS)
# AC_SUBST(HDF5_TYPE)
# AC_DEFINE(HAVE_HDF5)
#
# and sets with_hdf5="yes". Additionally, the macro sets
# with_hdf5_fortran="yes" if a matching Fortran wrapper script is found.
# Note that Autoconf's Fortran support is not used to perform this check.
# H5CC and H5FC will contain the appropriate serial or parallel HDF5
# wrapper script locations.
#
# If HDF5 is disabled or not found, this macros sets with_hdf5="no" and
# with_hdf5_fortran="no".
#
# Your configuration script can test $with_hdf to take any further
# actions. HDF5_{C,CPP,LD}FLAGS may be used when building with C or C++.
# HDF5_F{FLAGS,LIBS} should be used when building Fortran applications.
#
# To use the macro, one would code one of the following in "configure.ac"
# before AC_OUTPUT:
#
# 1) dnl Check for HDF5 support
# AX_LIB_HDF5()
#
# 2) dnl Check for serial HDF5 support
# AX_LIB_HDF5([serial])
#
# 3) dnl Check for parallel HDF5 support
# AX_LIB_HDF5([parallel])
#
# One could test $with_hdf5 for the outcome or display it as follows
#
# echo "HDF5 support: $with_hdf5"
#
# You could also for example, override the default CC in "configure.ac" to
