+SUMMARY="A Python library for creating 'editable wheels'"
+DESCRIPTION="This library supports the building of wheels which, when installed, will expose \
+packages in a local directory on 'sys.path' in 'editable mode'. In other words, changes to the \
+package source will be reflected in the package visible to Python, without needing a reinstall."
