-* Roadmap                                                               :old:
-  I moved the roadmap to [[file:README.org][README]].
-
-** DONE Write a function to look the symbol at point [3/3]
-   - [X] add a racket-helpdesk-online
-   - [X] add keyboard shortcuts to key maps
-   - [X] check/add documentation
-
-** DONE Finish the [[file:example/example.org][example]] on random networks
-** DONE Fix the generation of interaction graphs
-** DONE Setup =dds= as a package
-   - https://blog.racket-lang.org/2017/10/tutorial-creating-a-package.html
-** DONE Make =raco test= play nicely with my tests
-** DONE Replace =let= with =test-begin= in tests
-** DONE Initialise the random seed in each =test-case=
-   As of [2020-05-24 Sun], I have the impression that the seed is not
-   globally set.
-
-** DONE Factor out the code for functions
-** DONE Move =boolean-power= and =boolean-power-stream= to =utils=
-** DONE Tabulate multiple functions with the same domain
-** DONE Think about interactions between Racket code blocks
-   When a code block calls another code block, the result seems to be
-   dumped to a string.  This means that I cannot directly use the
-   result from calling a block, and that I have to do some writing and
-   reading between the two.
-
-   Check [[/home/scolobb/Candies/Science/People/Ion/rs-control/rs-control.org][rs-control.org]] to see what quick fixes I did recently.
-** DONE Make shortcuts for TBF/TBN and SBF/SBN
-** DONE Implement drawing the interaction graphs of TBN
-** DONE Implement truth tables grouped by Nai
-   Number of activated inputs in the Boolean input vectors.  Mainly to
-   illustrate how abstract representation works and breaks.
-
-** DONE Review =build-interactive-process-graph=
-   This function includes context sequences in states to differentiate
-   between the same states appearing at different steps of the
-   interactive process.  In fact, I don't care about that at all,
-   because if I want to have the complete interactive process, I can
-   just use =build-interactive-process=.
-
-   /Comment on <2020-11-09 Mon>/: Yeah, but I need the context
-   sequence in the state to be able to define the dynamics properly.
-   This actually shows that the context sequence must be part of the
-   state if we want to capture reaction systems in the framework of
-   discrete dynamical systems.
-
-   Secondly, =build-interactive-process-graph= assumes that the input
-   context sequence is a /prefix/ of an infinite context sequence in
-   which the majority of contexts are empty.  This is a rather weird
-   assumption.
-
-   Because of these two aspects, I found that this function was rather
-   useless in working with actual reaction systems, in particular in
-   my collaboration with Ion on control of reaction systems.
-
-** 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]]
