Quicklisp Global Install (aka the road to a real debian package). Replace + with / in filenames.

# Maybe put the /usr/share/quicklisp/ folder straight in the package.
# quicklisp is downloaded in /usr/share/quicklisp/quicklisp so that /usr/share/quicklisp is available
# for other files, such as the helpers for quickloading global systems.

# The quicklisp.lisp file should be in /usr/share/quicklisp/, so that it's reusable
# for local installs. See /usr/bin/ql-local-install
