+** Roadmap
+   Here is my current roadmap for this toolkit, in order.  The first
+   element is what I am currently working on.  The degree of certainty
+   that I work on the subsequent items decreases with their position
+   in the list.
+
+*** TODO Review =build-interaction-graph=
+    Check that the definition of this function really follows the
+    definition of the interaction graph.  Pay attention to the
+    existential vs. universal quantifiers.
+*** TODO Write the docs properly with Scribble
+    https://docs.racket-lang.org/scribble/srcdoc.html
+*** TODO Submit =update-graph= to =stchang=
+*** TODO Implement the BN \to RS conversion
+*** TODO Implement the minimisation of TBF/SBF
+*** TODO Contribute to Racket
+    - Make sequence-filter allow multivalued sequences, provided the
+      arity of the predicate is consistent with the arity of
+      the sequence.
+    - Add a sequence->hash function that accepts a multivalued
+      sequence of keys and values (exactly like what in-hash produces)
+      and copies them into a hash table.
+*** TODO Test network inference with [[https://docs.racket-lang.org/racklog/index.html][Racklog]]
