nbflow

Uses __depends__ and __dest__ variables in notebooks to clearly define inputs and outputs, simplifying workflow specification and ensuring reproducibility.

Leverages Scons for robust dependency management, automatically executing notebooks only when dependencies change, which minimizes unnecessary runs.

Supports both Python 2 and 3, with Scons 3.0.0+ enabling compatibility with modern Python 3.5+ environments, as noted in the README update.

Automates entire notebook pipelines with a single 'scons' command, reducing manual steps and enhancing consistency in data analysis.
