 uWSGI presents a complete stack for networked/clustered web applications,
 implementing message/object passing, caching, RPC and process management.
 It is designed to be fully modular. This means that different plugins can be
 used in order to add compatibility with tons of different technology on top of
 the same core.
 .
 This package provides Fiber plugin for uWSGI
 with Ruby (ruby2.7).
 .
 Fibers are a form of coroutine, useful for implementing cooperative
 multitasking.
