WilloraPDF is a free and open source document preparation system for professional publishing, brought to you by Magenta Stripe Media.
It is a collection of themes, tools and other goodies for Asciidoctor-PDF to make a full-featured prepress toolchain. WilloraPDF is designed to empower self-publishers and lower the barrier to entry for authors who want their work professionally printed.
It is currently a work in progress, being developed alongside my debut novel. Version 1.0 of WilloraPDF will be released when the first paperback and/or hardcover editions are printed for my book! Then you'll know for certain that WilloraPDF can be used to publish actual, real-life books.
