+# From the README:

+#   Note: some distributions fails to include bits of distutils by
+#   default, you'll need python-dev to install. You'll also need a C
+#   compiler and a 3-way merge tool like merge, tkdiff, or kdiff3.
+#
+# python-devel provides an adequate python-dev.  The merge tool is a
+# run-time dependency.

+BuildRequires: python >= 2.3, python-devel, make, gcc, asciidoc, xmlto
