Fair enough.

CDR6 is http://cdr.eurolisp.org/document/6/index.html

About OS detection in *features*, I don't know how it is supposed to work.

This happens to me too with recent versions from SVN. I guess it's a bug.

You can (require 'asdf), which should load the version of asdf bundled
with abcl (which afaik is an older version without the long form of
d-m-c).

I'm interested in this too. I used to use Eclipse for the Java parts,
but I'm moving more and more to Emacs (and simply Ant to build/run).
However, I have a very minimal .emacs setup (I'm an Emacs newbie).
