AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized. Output is specified with a Scheme-enhanced output template. Input, if required by your template, may come from AutoGen definitions, CGI data, or XML files.
Spiritbot is a suite of agent/bot applications with an IRC core. The core component interacts with a natural language chat interface (Scheme/LISP) base that parses input natural language (chat) input and then tries to come up with valid responses. The focus of the chat centers on technology.
