Thanks!

I haven't been able to write a Mapping Guide for the project yet.  I
should probably make that URL text to avoid confusion until it's done.

Yes, you should be able to generate Gentoo ebuilds from Lispy.
Everything you need is in the map.  The only issue is Gentoo/Debian
use symlinks from /usr/share/common-lisp/systems/ into
/usr/share/common-lisp/source/... and then add only
/usr/share/common-lisp/systems/ to asdf:*central-registry*.

You can probably take two approaches with that:

1. With the Lispy map, parse :asdf-paths and create similar symlinks
2. Maintain an ASDF configuration file like Lispy's own
asdf-config.lisp (IIRC, the ebuilds in Gentoo for Emacs take a similar
approach).

If you go the second way you might want an
/etc/lispy.d/NNpackagename.lisp-expr installed for each generated
package installed.  Each might contain the :asdf-paths which you would
concatenate into, for example, /etc/lispy.lisp.
