Feature description

There are tools which can generate the dependency list automatically: https://github.com/mikepenz/AboutLibraries

Why do you want this feature?

NewPipe is required to list used libraries and dependencies for licensing reasons. This is done in the AboutFragment. When adding, removing or updating libraries the library list needs to be updated as well. This is often forgotten.
