Output for this "class" of tool (gsymutil as well) probably ought to be structured to better support tooling validation. This is step one. I'm happy to make a shorter alias for `--json-error-summary-file` (`-j` ?). I do think that the file format @clayborg suggested (and I adopted) can be extended to easily include full details for each error.
