Mayura stands on the work of many open-source projects. This page credits the main ones: what Mayura uses each one
for, and its license. Every project keeps its own copyright and license terms; Mayura itself is licensed under
Apache-2.0. The exact versions are pinned in the repository's lockfile.

## Installed with Mayura

`npm install mayura` installs these, and nothing else.
