+ PR 79</link>: Switched from Ant, to Gradle. IDE setup now
+ involves no lengthy manual adjustments, assuming it's fairly
+ recent IDE with decent Gradle support. There's on
+ <literal>build.properties</literal> to set up either, but
+ you need to ensure that you have both JDK 8, and JDK 16m and
+ that Gradle finds them. See the <literal>README.md</literal>
+ for more instructions. (Gradle itself is self-installing, of
+ course.)</para>
