+    #   If auto_template is true then template is ignored and the SPDX

+    #   their license info JSON, if it is not then we will use the full
+    #   licenseText to generate the header which works fine for short
+    #   licenses like MIT but can be quite lengthy for other licenses
+    #   like BSD-4-Clause. The above default template is valid for most
+    #   licenses and is recommended for MIT, and BSD licenses. Common
