Use: "pack <package name>",
Short: "pack a custom package",
Long: `Pack creates a package from a directory, generating the metadata required from a tree to generate a repository.
Pack can be used to manually replace what "luet build" does automatically by reading the packages build.yaml files.
$ mkdir -p output/etc/foo
$ echo "my config" > output/etc/foo
$ luet pack foo/bar@1.1 --source output
Afterwards, you can use the content generated and associate it with a tree and a corresponding definition.yaml file with "luet create-repo".
