+/* This REPL was adapted from an old (2008-ish) version of the Scala
+ * REPL. The original version from which the adaptation was done is found in:
+ *
+ *      https://github.com/odersky/legacy-svn-scala/tree/spoon
+ *
+ * The reason this version was picked instead of a more current one is that
+ * the older version is much smaller, therefore easier to port. It is also
+ * considerably less intertwined with nsc than later versions.
+ *
+ * There are a number of TODOs:
+ *
+ *  - re-enable bindings (urgent, easy)
+ *  - re-enable jline support (urgent, easy)
+ *  - create or port REPL tests (urgent, intermediate)
+ *  - copy improvements of current Scala REPL wrt to this version
+ *    (somewhat urgent, intermediate)
+ *  - make string generation more functional (not urgent, easy)
+ *  - better handling of ^C (not urgent, intermediate)
+ *  - syntax highlighting (not urgent, intermediate)
+ *  - integrate with presentation compiler for command completion (not urgent, hard)
