(@pxref{Substitutes}). This makes it possible it to profile disk usage of
store items that are not even on disk, only available remotely.
You can also specify several package names:
@example
$ guix size coreutils grep sed bash

/gnu/store/@dots{}-readline-6.3 67.6 1.2 1.2%
@dots{}
total: 102.3 MiB
@end example
