%description
Incus is a system container manager. It offers a user experience
similar to virtual machines but uses Linux containers (LXC) instead.

%package tools
Summary:        Optional extra tools for %{name}

%description tools
Extra tools to help with the administration of Incus. This includes helpers for
migrating from LXD to Incus as well as a smattering of other helpers that can
be helpful for some users but are not necessary for most Incus deployments
(such as benchmarking tools and tools for managing simplestreams Incus image
servers).
