Vellum 2.0.7 | Mac OS X | 12 MB.
Vellum is an eBook-generating tool that lets you easily create an eBook from a text manuscript or from scratch within the application. Choose the appropriate style from several options, view instant previews of the finished product, and easily generate and regenerate eBooks with a single click to avoid disaster upon finding mistakes.
Not a word processor, nor is a design program.
Rather, it is an application to convert your finished manuscript into a beautiful eBook.
