At least one Linux distribution (Arch) has made python 3 the default
interpreter, and Debian and Ubuntu have expressed a desire to eventually
make this the case. As such, invoking 'python' or '/usr/bin/python'
will possibly run python 3 instead of version 2.
Distributions have included a 'python2' link for quite some time now,
and given that we have some scripts that require python 3, we should be
explicit about those that require python 2.
In addition, be more consistent about how python is invoked, preferring
the:
#!/usr/bin/env python2
construct rather than a hardcoded path to python. This allows the user
to have an alternative python in their path that will be used in
preference to the system provided version.
