I agree that this is worth improving, but I'm not sure what your
suggestion is; do you mean that --config would take a config argument
(like build-config does), and apply that config similar to the pipeline
you suggested above?

I think that would be annoying since it would require you to always
specify the config.

In my current usage, I've used Tom's config to make my tla source tree,
but I don't really want to use the original config after that, because
I've replaced parts of the tree with my own.

Because of this I use a similar, but crucially different, pipeline:

   tla inventory --trees --nested | xargs -n1 tla CMD --dir

For this particular usage, a similar `--nested' option would be very
convenient, e.g., the above would be replaced by:

   tla CMD --nested

As for --config, well, I'm not yet a willing user, so I'll leave that
to others, but it does seem like it would be annoying to have to keep
track of the config; maybe if build-config stashed away the config name
in {arch}/=current-config it could be read by --config or something...
