+#
+# SYNOPSIS
+#
+#   AX_PKG_SWIG([major.minor.micro], [action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   This macro searches for a SWIG installation on your system. If found,
+#   then SWIG is AC_SUBST'd; if not found, then $SWIG is empty.  If SWIG is
+#   found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd.
+#
+#   You can use the optional first argument to check if the version of the
+#   available SWIG is greater than or equal to the value of the argument. It
+#   should have the format: N[.N[.N]] (N is a number between 0 and 999. Only
+#   the first N is mandatory.) If the version argument is given (e.g.
+#   1.3.17), AX_PKG_SWIG checks that the swig package is this version number
+#   or higher.
+#
+#   As usual, action-if-found is executed if SWIG is found, otherwise
+#   action-if-not-found is executed.
+#
+#   In configure.in, use as:
+#
+#     AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ])
+#     AX_SWIG_ENABLE_CXX
+#     AX_SWIG_MULTI_MODULE_SUPPORT
+#     AX_SWIG_PYTHON

+#
+# DESCRIPTION
+#
+#   Makes sure that python supports the version indicated. If true the shell
+#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
+#   ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by
+#   running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
+#
+#   Example:
+#
+#     AC_PATH_PROG([PYTHON],[python])
+#     AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ])
+#
+#   This will check to make sure that the python you have supports at least
+#   version 2.4.4.
+#
+#   NOTE: This macro uses the $PYTHON variable to perform the check.
+#   AX_WITH_PYTHON can be used to set that variable prior to running this
+#   macro. The $PYTHON_VERSION variable will be valorized with the detected
+#   version.

+# 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.
