 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."
