ASDF Systems

ASDF finds systems in ~/common-lisp/, ~/.local/share/common-lisp/source/, Quicklisp's local-projects/, or directories registered in asdf:*central-registry* / source-registry configuration.

UIOP (shipped with ASDF) provides portable utilities: files, pathnames, run-program, environment variables, and command-line arguments.
