Castoway for Mac

From Pound Hill Software:

Castoway brings order to the planning process through job management data tracking, pre-design estimating tools, and with the optional CastowayLink, automated page and style sheet generation in QuarkXPress.
An ideal page count estimating tool, Castoways built-in standard book styles library offers the designer the chance to try out numerous design specifications prior to diving into an application such as QuarkXPress to do the layout. If no stock style fits, build a new one to your specifications.
Besides calculating and displaying specifications as design scenarios are tried out, design parameters can be saved along with standard job management data and output in the Composition Specification form.
Castoway represents a truly efficient design environment and way to communicate layout specifications to layout artists, editors, and writers.
