Publisher's Description:

> PowerLisp 2.02 includes CLOS support (conforming to the Metaobject
> Protocol documented in "The Art of the Metaobject Protocol").
> PowerLisp is a Common Lisp development environment for the
> Macintosh. It consists of a Common Lisp interpreter, native-code
> PowerPC compiler, PowerPC macro assembler, disassembler, incremental
> linker and multi-window text editor. It requires a PowerMac (the
> older version 2.01 supports 68k Macs).
>
> PowerLisp has the ability to run in the background. While executing
> a Common Lisp program, the user may switch to another application as
> it continues to run.
>
> PowerLisp is extremely fast. All compiled PowerLisp functions
> execute as native machine instructions. The speed is comparable to
> other fully compiled languages.
