Tentative support for primary-system-name.

Pull request for #7

What version of ASDF does this require?

[fare]

2.27 or later, i.e. won't work with quicklisp-bootstrap's currently bundled 2.26, but will work with the 3.0.3 I see in quicklisp-controller.

[quicklisp]

I get an error indicating that PRIMARY-SYSTEM-NAME is not external.

(I would really like everyone to adopt ASDF 3 and see ASDF 2 die. So far, the last pockets of resistance are LispWorks and Quicklisp. I filed a bug against LispWorks.)

[quicklisp]

I resist because ASDF3's new features break my software.

[fare]

Which software is broken by what feature? I'm willing to help.

[fare]

It's external in asdf/find-system. I'll export it from asdf in next release.

[quicklisp]

The slashed system magic breaks the system installation database of Quicklisp.

Fixing it isn't just a matter of making the current client work. It must be made easy to go back to previous versions of the client and previous versions of ASDF to make sure that previous software dists remain loadable.

That represents a few days of thinking and new work. I'd rather not get it as an untested patch from an outside source.

With this patch, I can't build LIL - it blows up the stack. The bottom frames are here: http://report.quicklisp.org/lisp-interface-library/2014-01-04/failtail.txt

I can post more if necessary.
