A full and final answer[*] to all the people who keep asking
for slightly tangential software to be added to contrib: to
wit, a contrib module to automate the downloading and
installing of packages that are _not_ part of contrib.
* (require 'asdf-install)
* (asdf-install:install 'xlunit)
or
$ sbcl-asdf-install xlunit
See contrib/asdf-install/README for more details and scary
security-related muttering.
Also added a :INITIAL-FUNCTION to SB-EXECUTABLE:MAKE-EXECUTABLE
so that files don't have to be written such that the
application starts as soon as they're loaded
[*] Ha!
