+# Description:
+# This script automates the process of uploading VeraCrypt release packages
+# to Launchpad. It authenticates with Launchpad, locates the appropriate
+# project, series, milestone, and release, and then uploads all package files
+# from a specified directory, skipping any that have already been uploaded.
