How It Works
Sienna\Dyn has a modular framework with five core packages written in the Julia programming language. Use whichever combination is right for your use case. All packages are open-source, free to use, and have a command-line interface. See the Sienna Documentation Hub for each package's documentation, general installation instructions, and tutorials.
