Attribute set of i3status-rust bars, each with their own configuration.
Each bar <varname>name</varname> generates a config file suffixed with
the bar's <varname>name</varname> from the attribute set, like so:
<filename>config-<replaceable>name</replaceable>.toml</filename>.
</para><para>
This way, multiple config files can be generated, such as for having a
top and a bottom bar.
