+- Adds support for `--no-transforms` (`-T`) which generates bundles with
+  original sources.
+  A future version of `@endo/import-bundle` will be able to execute this
+  kind of bundle on XS and in Node.js, but will remain opt-in because
+  they cannot be made to run on the web without further work on module
+  virtualization in the platform without entraining a client-side
+  dependency on a JavaScript parser framework (namely Babel).
