+%description
+Python helpers to limit the number of threads used in the
+threadpool-backed of common native libraries used for scientific computing
+and data science (e.g. BLAS and OpenMP).
+Fine control of the underlying thread-pool size can be useful in
+workloads that involve nested parallelism so as to mitigate
+oversubscription issues.
