Library

In this tutorial you'll get familiar with:

• Refactoring your Rust project into multiple libraries (crates)
• Running applications on the command-line
• Parsing command line paramenters by hand
• Re-using existing crates in your application
• Learn about borrowing

We start with a command-line tool that takes an image and a filter name as input. It applies the given filter to the image and produces an output.png.
