+SUMMARY="A library to access the metadata for a Python package"
+DESCRIPTION="importlib_metadata is a library which provides an API for \
+accessing an installed package’s metadata (see PEP 566), such as its entry \
+points or its top-level name. This functionality intends to replace most \
+uses of pkg_resources entry point API and metadata API. Along with \
+importlib.resources in Python 3.7 and newer (backported as \
+importlib_resources for older versions of Python), this can eliminate \
+the need to use the older and less efficient pkg_resources package."
