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.
This requires pysetuptools.
Circular dependencies warning: The DOCS=yes flag needs 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.
