+# Asumptions for this script: 
+# 1. directory_name is scanned directory.
+#  Files are copied to this directory with full tree. As result, if we find
+#  license offender, we can have full path (just scrape directory_name). We do this
+#  magic because scancode allows to scan directories/one file.
+# 2. SPDX and license text is a must for all code files
