Compiler settings

We use sbcl 2.2.9.debian to compile your program with the following command:

$ sbcl --noinform --noprint --non-interactive --eval "(require :asdf)" --eval "(if (equal (compile-file \"{file}\") NIL) (sb-ext:exit :code 1) ())"

• {file} is each file (the command is run once per file).

• {mainfile} is the entrypoint file (you can specify which file this is when submitting).
