Subject: swc-installation-test-2.py: Don't chain exceptions (yet)
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=749bddffc9981b5212abba476f1323736c156f9b;p=swc-boot-camp.git

swc-installation-test-2.py: Don't chain exceptions (yet)

Exception chaining (PEP 3134, 'raise ... from') raises SyntaxErros in
Python 2.x.  Comment the chaining out until SWC starts teaching only
Python 3.x.
