+%global _description %{expand:
+This is a backport of the BaseExceptionGroup and ExceptionGroup classes from Python 3.11.
+
+It contains the following:
+
+- The exceptiongroup.BaseExceptionGroup and exceptiongroup.ExceptionGroup
+  classes
+- A utility function (exceptiongroup.catch()) for catching exceptions possibly
+  nested in an exception group
+- Patches to the TracebackException class that properly formats exception
+  groups (installed on import)
+- An exception hook that handles formatting of exception groups through
+  TracebackException (installed on import)
+- Special versions of some of the functions from the traceback module, modified
+  to correctly handle exception groups even when monkey patching is disabled,
+  or blocked by another custom exception hook:
+    - traceback.format_exception()
+    - traceback.format_exception_only()
+    - traceback.print_exception()
+    - traceback.print_exc()
+
+If this package is imported on Python 3.11 or later, the built-in
+implementations of the exception group classes are used instead,
+TracebackException is not monkey patched and the exception hook won’t be
+installed.
+
+See the standard library documentation for more information on exception
+groups.}
