This is a plugin for boto, which has been deprecated for years,
and is broken and due for removal.

No release in four years and depends on the deprecated and broken
boto package; to quote the README:

> ## Where are the maintainers ?
>
> Qubole was acquired. All the maintainers of this repo have moved
> on. Some of the employees founded ClearFeed. Others are at big data
> teams in Microsoft, Amazon et al.

Marked as broken for months, and depends on boto which has been
deprecated for years and is now also broken and due for removal.

No release in almost half a decade, no maintainer in Nixpkgs, and
the README describes it as obsolete and recommends alternatives:

No release since 2017 and deprecated upstream; see
<kubernetes-sigs/kubespray@1869aa3#diff-a39c9f7aa728d5fa3b973bc6ba49228a>.

This package has been broken since 24.05 (`pkg_resources` error when
running `toil --help`), and hasn’t built since Python 3.12 became
the default. There have been two major upstream releases since this
package was last updated. I tried to package the newest version, which
drops the boto dependency, but unfortunately it requires obsolete
versions of other Python libraries that we no longer package. Since
it’s been broken for this long anyway and can’t be updated,
let’s drop it for now.

Boto has not seen a release since 2018, and has been officially
marked as deprecated in favour of boto3 and botocore since 2021. It
has required downstream patching to keep it running on newer Python
versions and is broken on the new default of Python 3.12. It also
requires the obsolete nose test framework that we are in the process
of removing.

The few packages we carry that still require boto are in poor upstream
maintenance state and some of those were already broken. The NixOps
AWS plugin was the last holdout that justified keeping this package,
but it is now also broken.
