+#
+# SYNOPSIS
+#
+#   AC_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_LDFLAGS) 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.
