## Overview

This repository is a collection of TVBox/OK影视 configuration resources and provider scripts, not a media-hosting service. The documented user workflow is to subscribe to a configuration in a compatible client, use provider scripts to discover and select content, and obtain playback links from external sources. The JavaScript runtime includes the drpy engine and parsing/encoding helpers; separate JavaScript, Python, and library directories hold provider implementations. Several configuration files named in the README are not present in the supplied tree, and most provider implementations were not sampled, so those relationships are shown only where documented or marked unverified.

Main entry points: [`JS/drpy2.js`](https://github.com/gaatyin/tomorrow/blob/master/JS/drpy2.js) (drpy engine), [`JS`](https://github.com/gaatyin/tomorrow/tree/master/JS) (JS site adapters), [`lib`](https://github.com/gaatyin/tomorrow/tree/master/lib) (Library adapters), [`py`](https://github.com/gaatyin/tomorrow/tree/master/py) (Python adapters)
