Lisp Implementation Documentation

Included in libstephen (for some reason) is a somewhat functional lisp implementation. This feature is intended to provide some lightweight scripting capabilities for applications using the library, without having to link to a more complex tool like Python or Lua.

For instance it may be possible for an application to write all its routines in a way that they are callable from libstephen’s lisp interpreter, and then to run the main program as a small lisp script. Or an application could use the lisp implementation as a powerful and easy to use configuration language for startup. A final possibility might be enabling extensions and plugins for an application.

This section is organized so that the documentation required for a library user to embed the interpreter is presented first. More advanced information about the inner workings of the interpreter is presented later.
