Print all implicit and explicit tween objects used by a Pyramid

explicit tweens ordering (will be true when the "pyramid.tweens"
deployment setting is used) or an implicit tweens ordering (will be true
when the "pyramid.tweens" deployment setting is *not* used).
This command accepts one positional argument named "config_uri" which
specifies the PasteDeploy config file to use for the interactive
shell. The format is "inifile#name". If the name is left off, "main"
will be assumed. Example: "ptweens myapp.ini#main".
