and simulator (TLC); a TLA+ REPL; a semantic analyzer (SANY); the TLATeX
typesetting system; PlusCal translator; and more.  I have added five
wrapper scripts for convenience, rather than invoking `java' manually.
The wrapper scripts are not comprehensive; users who are familiar with
tla2tools.jar, or have read the book Specifying Systems, may still
invoke the commands in the traditional way.

The minimum JDK version is 11.  I chose to stick with that rather than
bumping it to 14 (which is the largest version currently in Guix)
because each OpenJDK version in Guix depends on the version before it,
and so it needlessly results in many 100s of MiB of unnecessary
dependencies.

Note that this is _not_ the TLA+ Toolbox, which is the GUI commonly used
with TLA+.

* gnu/packages/java.scm (tla2tools): New variable.
* gnu/packages/patches/tla2tools-build-xml.patch: New patch.
* gnu/local.mk (dist_patch_DATA): Add it.
