<title>Description</title>
<para>
Unlike other flatpak commands, <command>flatpak-spawn</command> is available
to applications inside the sandbox. It runs <arg choice="plain">COMMAND</arg>
outside the sandbox: either in another sandbox, or on the host.
</para>
<para>
When called without <option>--host</option>, <command>flatpak-spawn</command>
uses the Flatpak portal to create a copy of the sandbox it was called from,
optionally using tighter permissions and optionally the latest version of the
app and runtime (see <option>--latest-version</option>).
