+You can run a regression test on the code with 'make check'. Extreme
+care has been taken to not silently change gameplay. By policy, all
+user-visible changes from 2.5 are revertible with the -o (oldstyle)
+option.
+
+If you encounter a bug (not likely; thuis code is old and well tested)
+please try to make a test log that reproduces it, using the -l option,
+and ship it to the maintainers.
