A book build system that produces PDF, EPUB and MOBI from asciidoc to Amazon specifications.
Try:
$ make LANG=en pdf
$ make LANG=es epub
The build system (/conf, Makefile) is forked and heavily modified from https://github.com/akosma/eBook-Template, which is public domain. The derivative work that adapts it for Amazon Createspace publishing is licensed under an MIT license.
