*** DEPRECATION WARNING ***

Cookiecutter data science is moving to v2 soon, which will entail using
the command `ccds ...` rather than `cookiecutter ...`. The cookiecutter command
will continue to work, and this version of the template will still be available.
To use the legacy template, you will need to explicitly use `-c v1` to select it.

Please update any scripts/automation you have to append the `-c v1` option,
which is available now.

For example:
    cookiecutter -c v1 https://github.com/drivendata/cookiecutter-data-science
