+By design asyncio does not allow its event loop to be nested. This presents a
+practical problem: When in an environment where the event loop is already
+running it's impossible to run tasks and wait for the result. Trying to do so
+will give the error "RuntimeError: This event loop is already running".
+
+The issue pops up in various environments, such as web servers, GUI
+applications and in Jupyter notebooks.
+
+This module patches asyncio to allow nested use of asyncio.run and
+loop.run_until_complete.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
