Hi!
We started working on a new community fork of the Cookiecutter project, named Cookieninja.
The fork is found at: https://github.com/cookieninja-generator/cookieninja

We have re-opened and merged your PR in the Cookieninja project at cookieninja-generator/cookieninja#30

We're trying to bring the life back to this amazing project.
We are committed to reviewing and merging each PR in up to 2 weeks from the day it's opened (if there are no issues with it).
We'd really like you to join the fork, star it and contribute to it!

Thank you :)

@jensens @ericof @browniebroke @pydanny Please merge this PR.

It appears to resolve an existing bug. #1754 can be closed manually after this merges (it is not a linked issue and will not close automatically when this merges).

Please don't @ me, while I'm a member of the organisation, I'm not a maintainer of the cookiecutter CLI project.

My apologies!! It won't happen anymore. You're correct, I was looking at members of the organization.

Please have a good weekend!
