CLON (Common Lisp Object Network) is a prototype-based object system for Common Lisp written by David O'Toole. The details of inheritance, message passing, and field lookup are inspired by the Io language and the Garnet UI toolkit (KR in particular). It doesn't seem to be available anywhere. CLON is used in RLX, a game engine for rogue-like games.
Clon - the Command-Line Options Nuker
Clon is a library for managing command-line options in standalone Common Lisp applications. It provides a unified option syntax with both short and long names, automatic completion of partial names and automatic retrieval/conversion of option arguments from the command-line, associated environment variables, fallback or default values. Clon comes with a set of extensible option types (switches, paths, strings etc.). Clon also provides automatic generation and formatting of help strings, with support for highlighting on tty's through ISO/IEC 6429 SGR. This formatting is customizable through "themes".
