-**** TODO SQL conversion
+**** SQL conversion -- not compatible with codeql v2.13.4
+     The ultimate purpose of the sarif-cli is producing CSV files for import into
+     SQL databases.  This requires a completely defined static structure, without
+     any optional fields.  The internals of the tool are beyond the scope of this
+     workshop, some details are their external effects are important:
+
+     1. a (very large and comprehensive) type signature is defined in sarif-cli
+     2. sarif files that have extra fields not in the signature will produce warnings
+     3. sarif files that are missing fields from the signature will produce a fatal 
+        error.  A message will be printed and the scripts will abort.
+     4. Sometimes, sarif files will have a field but no content.  For a number of
+        these, dummy values are inserted.  One example are queries that don't
+        produce line numbers in their output; for those, -1 is used as value.
+
+     Unfortunately, this version of codeql
