+Jinja2 is a template engine written in pure Python. It provides a
+Django inspired non-XML syntax but supports inline expressions and
+an optional sandboxed environment.
+
+Circular dependencies warning: The DOCS=yes flag needs the optional
+dependency Sphinx, which needs Jinja2, which needs Sphinx because
+DOCS=yes ... So... If you really need the docs, build Jinja2
+without the DOCS=yes flag, build Sphinx, then rebuild Jinja2 with
+DOCS=yes. Incidentally, unless you are a developer, you don't
+normally need the DOCS=yes flag.
