Subject: swc-installation-test-2.py: Add TornadoPythonPackage for version extraction
X-Git-Url: http://git.tremily.us/?p=swc-setup-installation-test.git;a=commitdiff_plain;h=a6b5a14638d4857f34b67e9bf0040c1212e1782d

swc-installation-test-2.py: Add TornadoPythonPackage for version extraction

Tornado follows Python's example with tornado.version and
tornado.version_info instead of using tornado.__version__.  While we
could parse tornado.version with our usual machinery, take advantage
of the pre-parsed version_info by defining a new class.
