-dnl @synopsis AC_PYTHON_DEVEL([version])
-dnl
-dnl Checks for Python and tries to get the include path to 'Python.h'.
-dnl It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) output
-dnl variables. Also exports $(PYTHON_EXTRA_LIBS) and
-dnl $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
-dnl
-dnl You can search for some particular version of Python by passing a
-dnl parameter to this macro, for example ">= '2.3.1'", or "== '2.4'".
-dnl Please note that you *have* to pass also an operator along with the
-dnl version to match, and pay special attention to the single quotes
-dnl surrounding the version number.
-dnl
-dnl If the user wants to employ a particular version of Python, she can
-dnl now pass to configure the PYTHON_VERSION environment variable. This
-dnl is only limited by the macro parameter set by the packager.
-dnl
-dnl This macro should work for all versions of Python >= 2.1.0. You can
-dnl disable the check for the python version by setting the
-dnl PYTHON_NOVERSIONCHECK environment variable to something else than
-dnl the empty string.
-dnl
-dnl If you need to use this macro for an older Python version, please
-dnl contact the authors. We're always open for feedback.

+# 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.
