1. Install SBCL and Quicklisp.
2. Clone or symlink https://github.com/sjl/cl-losh into your Quicklisp local projects directory.
3. Run make.
4. Run ./silt.

Recent versions of SBCL may have broken cl-charms' Unicode support, see this bug. Use an earlier version (1.8 ish) or scrub the codebase of fancy characters to get it working until someone debugs cl-charms.
