arachni web_ui missing?

[esmnemon]

Hi,
I just noticed that the arachni reference on the tools-site ( http://tools.kali.org/web-applications/arachni ) indicates that the web-ui is installed (and configured) after running
#apt-get install arachni (or the web-metapackage)

I cannot see that arachni_web utility is packaged in the arachni-package.
#grep arachni_web /var/lib/dpkg/info/arachni.list
#echo $?
1

Is this a mistake in the packaging-process, or is this the way it is meant to be (a doc-error?)

or.. Have I done anything wrong?

Thanks for building kali, it is awsome!
