+Shlax: Beautiful Async Subprocess executor
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Why?
+====
+
+In Python we now have async subprocesses which allows to execute several
+subprocesses at the same time. The purpose of this library is to:
+
+- stream stderr and stdout in real time while capturing it,
+- real time output must be prefixed for when you execute several commands at
+  the time so that you know which line is for which process, like with
+  docker-compose logs,
+- output coloration in real time with regexps to make even more readable.
+
+This code was copy/pasted between projects and finally extracted on its own.
+
+Demo
+====
+
+.. image:: https://yourlabs.io/oss/shlax/-/raw/master/demo.png
+
+You will find the demo script in demo.py in this repository.
+
+Usage
+=====
+
+Basics
+------
+
+Basic example, this will both stream output and capture it:
+
+.. code-block:: python
+
+    from shlax import Subprocess
+    proc = await Subprocess('echo hi').wait()
+    print(proc.rc, proc.out, proc.err, proc.out_raw, proc.err_raw)
+
+Longer
+------
+
+If you want to start the command and wait for completion elsewhere then call
+any of ``start()`` and ``wait()``, or both, explicitely:
+
+.. code-block:: python
+
+    proc = Subprocess('echo hi')
+    await proc.start()  # start the process
+    await proc.wait()   # wait for completion
+
+Proc alias
+----------
+
+Note that shlax defines an alias ``Proc`` to ``Subprocess`` so this also works:
+
+.. code-block:: python
+
+    from shlax import Proc
+    proc = await Proc('echo hi').wait()
+
+Quiet
+-----
+
+To disable real time output streaming use the ``quiet`` argument:
+
+.. code-block:: python
+
+    proc = await Subprocess('echo hi', quiet=True).wait()
+
+Prefix
+------
+
+Using prefixes, you can have real time outputs of parallel commands and at the
+same time know which output belongs to which process:
+
+.. code-block:: python
+
+    proc0 = Subprocess('find /', prefix='first')
+    proc1 = Subprocess('find /', prefix='second')
+    await asyncio.gather(proc0.wait(), proc1.wait())
+
+Coloration and output patching
+------------------------------
+
+You can add coloration or patch real time output with regexps, note that it
+will be applied line by line:
+
+.. code-block:: python
+
+    import sys
+    regexps = {
+        '^(.*).py$': '{cyan}\\1',
+    }
+    await asyncio.gather(*[
+        Subprocess(
+            f'find {path}',
+            regexps=regexps,
+        ).wait()
+        for path in sys.path
+    ])
+
+Where is the rest?
+==================
+
+Shlax used to be the name of a much more ambitious poc-project, that you can
+still find in the ``OLD`` branch of this repository. It has been extracted in
+two projects with clear boundaries, namely `sysplan
+<https://yourlabs.io/oss/sysplan>`_ and `podplan
+<https://yourlabs.io/oss/podplan>`_ which are still in alpha state, although
+Shlax as it now, is feature complete and stable.
