	Long: `Get downloads packages or modules for CUE or another language
to include them in the module's pkg directory.

Get requires an additional language field to determine for which
language definitions should be fetched. If get fetches definitions
for a language other than CUE, the definitions are extracted from
the source of the respective language and stored.
The specifics on how dependencies are fechted and converted vary
per language and are documented in the respective subcommands.
