+    (description
+     "Blockbuster is a Python package designed to detect and prevent
+blocking calls within an asynchronous event loop.  It is particularly useful
+when executing tests to ensure that your asynchronous code
+does not inadvertently call blocking operations,
+which can lead to performance bottlenecks and unpredictable behavior.
+
+It does this by wrapping common blocking functions
+and raising an exception when they are called within an asynchronous context.
+Note that Blockbuster currently only detects @code{asyncio} event loops
+and is tested only with CPython.")
