Installation of HTML-TEMPLATE 1. Probably the easiest way is (load "/path/to/html-template/load.lisp") This should compile and load HTML-TEMPLATE on most Common Lisp implementations. 2. With MK:DEFSYSTEM you can make a symlink from 'html-template.system' to your central registry and then issue the command (mk:compile-system "html-template") Note that this relies on TRUENAME returning the original file a symbolic link is pointing to. With AllegroCL 6.2 this will only work if you've applied all patches with (SYS:UPDATE-ALLEGRO). 3. You can also use ASDF instead of MK:DEFSYSTEM in a similar way: (asdf:operate 'asdf:compile-op :html-template) (asdf:operate 'asdf:load-op :html-template) After installing HTML-TEMPLATE you can LOAD the file "test.lisp" to check if everything works as expected. Complete documentation for HTML-TEMPLATE can be found in the 'doc' directory. HTML-TEMPLATE also supports Nikodemus Siivola's HYPERDOC, see and .
