+Name:           python-immutables
+Version:        0.20
+Release:        1%{?dist}
+Summary:        Immutable Collections
+# The entire source code is Apache-2.0, except pythoncapi_compat.h, which is
+# 0BSD. While this file is unbundled, it is a header-only library; its entire
+# contents are compiled into the binary RPM, and packaging guidelines treat it
+# as a static library. Its license therefore contributes to the license of the
+# binary RPM. See discussion in
+# https://src.fedoraproject.org/rpms/python-immutables/pull-request/2, and the
+# (Rust-specific but relevant) policy
+# https://docs.fedoraproject.org/en-US/legal/license-field/#_rust_packages.

+%global common_description %{expand:
+An immutable mapping type for Python.
+
+The underlying datastructure is a Hash Array Mapped Trie (HAMT) used in
+Clojure, Scala, Haskell, and other functional languages. This implementation is
+used in CPython 3.7 in the contextvars module (see PEP 550 and PEP 567 for more
+details).
+
+Immutable mappings based on HAMT have O(log N) performance for both set() and
+get() operations, which is essentially O(1) for relatively small mappings.}
