Was trying out python3 and was trying to add a new user via gmg. I was getting this error:

Traceback (most recent call last):

Did a little searching and noticed: ​https://www.codecademy.com/forum_questions/535b85237c82ca9f46000f87#answer-535ba57f52f86373e30012ce

In Python 3.x, input() replaces raw_input(), for input from the console.

So I edited mediagoblin/gmg_commands/util.py and changed the only raw_input occurrence to input, re-ran the gmg command, and it created the user successfully (or said it did anyway; haven't tested it yet :p).

Outside of this one situation, I'm not sure if raw_input affects anything else.

For certain types of tasks, it's helpful (and perhaps necessary) to be able to use Alembic's own tooling. We don't want users to have to use this often, but it's particularly helpful for developers. In particular, solving #5424 will probably require having access to Alembic's tool.

Attached is a patch which adds a gmg raw_alembic command. It's not recommended that everyone use it, but now it's an available option.
