Complete documentation for CL-FAD can be found in the 'docs' directory or at <https://edicl.github.io/cl-fad/>. CL-FAD also supports Nikodemus Siivola's HYPERDOC, see <http://common-lisp.net/project/hyperdoc/> and <http://www.cliki.net/hyperdoc>. 1. Installation 1.1. Probably the easiest way is (load "/path/to/cl-fad/load.lisp") This should compile and load CL-FAD on most Common Lisp implementations. 1.2. With MK:DEFSYSTEM you can make a symbolic link from 'cl-fad.system' and 'cl-fad-test.system' to your central registry (which by default is in '/usr/local/lisp/Registry/') and then issue the command (mk:compile-system "cl-fad") Note that this relies on TRUENAME returning the original file a symbolic link is pointing to. This will only work with AllegroCL 6.2 if you've applied all patches with (SYS:UPDATE-ALLEGRO). 1.3. You can also use ASDF instead of MK:DEFSYSTEM in a similar way (use the .asd files instead of the .system files). 1.4. Via QuickLisp: (ql:quickload :cl-fad) 2. Test CL-FAD comes with a small test suite. To start it just load the file "test.lisp" and evaluate (CL-FAD-TEST:TEST).
