Dear Maintainer,

your package declares a dependency on "install-info". However this
dependency should only be needed for info viewers, as they have to
care about updating the info index. Your package do not seem to
provide an info viewer hence the dependency on "install-info" is not
needed. Consider to remove it.

Many thanks,
