It is a bit unfortunate that they cannot directly set the configure phase

We shouldn't call bash ./configure directly because there is more software than you may realize that use Python, Perl, Scheme, or something else for their configure scripts. I would prefer to just use the shebangs, but Aux does not have a way to patch shebangs (yet), so I would instead just put a TODO.

One thing I'd like to devise is a way to pass arguments down the to derivation call so that we can use structuredAttrs for configure flags and such, as they means Aux doesn't need to worry about escaping and spaces, as it will Just Work since Nix does the proper escaping for us.

If you don't want to, can just put a TODO there.

Same thing, TODO for structuredAttrs if you want, so we don't need to concat things with spaces naively.

As a minor improvement quoting each argument is probably fine.

Should add an option for the command to run for unpacking, defaulting to tar xfz so that other formats can be unpacked (zip, deb, ...)

I would recommend using find instead as ls is really only for human output, and ls will often adjust names for better human consumption (if they are not alphanumeric).

Also the glob will fail if there are names with dashes in it, so it should be something like ls -d -- */, or else they will becomes arguments to ls
