as seen at freshmeat: "Gutenbook is a personal multi-stage project to design, prototype, and develop a GTK+-based desktop application for reading Project Gutenberg Etexts. Currently, development consists of advanced prototyping in Perl/GTK+." According to the author, Lee, this is the original codebase from which the other Gutenbook project started, but this one is purely focused on perl/gtk+ instead of multiple (incompatible) codebases.
Gutenbook-0.1 -- the original?
