+# ----------------------
+#
+# Removes all stored license content for all files with at least one "Source"
+# header, so that the build will automatically pull down the latest license
+# content when run. The license content downloaded may need to be manually
+# edited, particularly if dependency NOTICE files contain extra information
+# that need not be kept in Guacamole's NOTICE files.
+#
+# This script is expected to be manually invoked when updating the license data
+# of dependencies, particularly when dependencies are updated.
+#
+# USAGE:
+#
+#     path/to/clean-license-files.sh

+
+##
+## The directory containing this script and all license information. This
+## should be "doc/licenses/" within the guacamole-client source tree.
