Lingua Franca packages contain reusable reactor class definitions. Each package lives in its own GitHub repository and contains importable reactor classes plus some demo programs using these classes.
To use a package, clone the repo into your lf-packages directory in the root of your project or into
the directory pointed to by your LF_PACKAGES environment variable.
For example, for the video-py package:
git clone https://github.com/lf-lang/video-py.git
Alternatively, if your project is in a git repo, create a submodule:
git submodule add https://github.com/lf-lang/video-py.git
Then import the library reactors. For example:
import WebCam, VideoDisplay from <video-py>
