# Here we use Anaconda for our builds, since it provides the simplest
# interface for running different versions of Python. We could also use
# it for 2.7, but the Ubuntu system has installable 2.7 Qt4-GL, which
# allows for more complete testing.

# Size testing can be skipped by adding "[size skip]" within a commit message.
