+"""Python module for interacting with ETSI GS NFV-SOL004 compliant packages.
+
+This module provides a SOL004Package class for validating and interacting with
+ETSI SOL004 packages. A valid SOL004 package may have its files arranged according
+to one of the following two structures:
+
+SOL004 with metadata directory    SOL004 without metadata directory
