Flipa PDF Flipbook: Third-Party Open-Source Licenses
=====================================================

Flipa bundles the libraries below in assets/lib/. WordPress.org does not allow loading
scripts from a CDN, so they ship inside the plugin rather than being fetched at runtime.

Each library is minified. Guideline 4 asks that non-human-readable code be accompanied by
a link to its source, so the unminified upstream source and the exact pinned version are
listed for every one of them. Nothing here has been modified: these are the published
distribution files, byte for byte, at the versions named.
