Sometimes, it is need to quickly get the metadata of a subset of
packages, without resorting to a full-blown JSON query.
Introduce a new per-package (and per-filesystem) foo-show-info rule,
that otputs a per-entity valid JSON blob.
Note that calling it for multiple packages and.or filesystems at once
will not generate a valid JSON blob, as there would be no separator
between the JSON elements:
$ make {foo,bar}-show-info
{ "foo": { foo stuff } }
{ "bar": { bar stuff } }
However, jq is able to absorb this, with its slurping ability, which
generates an array (ellipsed and manualy reformated for readability):
$ make {foo,bar}-show-info |jq -s . -
[
{ "foo": { foo stuff } },
{ "bar": { bar stuff } }
]
