These tools are commonly used but don't require the other bind binaries.
Bind's libs are used, so they've also been split into an extra output.
The old version of host isn't maintained anymore and was removed From Debian

(My OCD kicked in today...)
Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.
I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.
I've tried to stay away from generated expressions (and I think I
succeeded).
Some specifics worth mentioning:
* cron, has "Vixie Cron" in its description. The "Vixie" part is not
mentioned anywhere else. I kept it in a parenthesis at the end of the
description.
* ctags description started with "Exuberant Ctags ...", and the
"exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
at the end of description.
* nix has the description "The Nix Deployment System". Since that
doesn't really say much what it is/does (especially after removing
the package name!), I changed that to "Powerful package manager that
makes package management reliable and reproducible" (borrowed from
nixos.org).
* Tons of "GNU Foo, Foo is a [the important bits]" descriptions
is changed to just [the important bits]. If the package name doesn't
contain GNU I don't think it's needed to say it in the description
either.
The BIND configure script finds extra dependencies in /usr/include and /usr/lib,
and activates additional features if it does. This may cause the build to fail
on systems that cannot use a chroot environment. Actively disabling those
additional features prevents this issue from occurring.
`selectVersion ./foo "bar"' instead of `import ./foo/bar.nix'.
* Replaced `with args' with formal function arguments in several
packages.
* Renamed several files to `default.nix'. As a general rule, version
numbers should only be included in the filename when there is a
reason to keep multiple versions of a package in Nixpkgs.
Otherwise, it just makes it harder to update the package.
