+// Unfortunately even though npm shims "bin" commands on Windows with auto-

+// first. So it's possible to publish executables via npm on all platforms
+// except Windows. I consider this a npm bug.
+//
+// My workaround is to add this script as another layer of indirection. It'll
+// be slower because node has to boot up just to shell out to the actual exe,
+// but Windows is somewhat of a second-class platform to npm so it's the best
+// I can do I think.
