  34 Greenlets are lightweight coroutines for in-process concurrent
  35 programming.
  36
  37 The "greenlet" package is a spin-off of `Stackless`_, a version of
  38 CPython that supports micro-threads called "tasklets". Tasklets run
  39 pseudo-concurrently (typically in a single or a few OS-level threads)
  40 and are synchronized with data exchanges on "channels".
  41
  42 A "greenlet", on the other hand, is a still more primitive notion of
  43 micro-thread with no implicit scheduling; coroutines, in other words.
  44 This is useful when you want to control exactly when your code runs.
  45 You can build custom scheduled micro-threads on top of greenlet;
  46 however, it seems that greenlets are useful on their own as a way to
  47 make advanced control flow structures. For example, we can recreate
  48 generators; the difference with Python's own generators is that our
  49 generators can call nested functions and the nested functions can
  50 yield values too. (Additionally, you don't need a "yield" keyword. See
  51 the example in `test_generator.py
  52 <https://github.com/python-greenlet/greenlet/blob/adca19bf1f287b3395896a8f41f3f4fd1797fdc7/src/greenlet/tests/test_generator.py#L1>`_).
  53
  54 Greenlets are provided as a C extension module for the regular unmodified
  55 interpreter.

  59 Who is using Greenlet?
  60 ======================
  61
  62 There are several libraries that use Greenlet as a more flexible
  63 alternative to Python's built in coroutine support:
  64
  65  - `Concurrence`_
  66  - `Eventlet`_
  67  - `Gevent`_

  73 Getting Greenlet
  74 ================
  75
  76 The easiest way to get Greenlet is to install it with pip::
  77
  78   pip install greenlet
  79
  80 Source code archives and binary distributions are available on the
  81 python package index at https://pypi.org/project/greenlet
  82
  83 The source code repository is hosted on github:
