+# As of Node 20, the --test parameter does not support globbing, and it does not
+# support variable Windows paths. We also cannot invoke the test runner
+# directly, because while it has an API, there's no way to force it to transpile
+# the Typescript into JavaScript before passing it to the runner.
+#
+# So we're left with this solution, which shells out to Node to list all files
+# that end in *.test.ts (excluding node_modules/), and then execs out to that
+# process. We have to exec so the stderr/stdout and exit code is appropriately
+# fed to the caller.
