Ox-leanpub is a Leanpub book exporter for Org mode. It allows you to write your material entirely in Org mode, and manages the production of the files and directories needed for Leanpub to render your book. I use this package to publish my books.

For a comprehensive introduction to publishing with Org mode and Leanpub, check out my book Publishing with Emacs, Org-mode and Leanpub!

Enwrite is a tool I wrote some time ago to publish a Hugo blog using Evernote. I don’t use it anymore since I switched to publishing my blog using Org-mode and ox-hugo, so it may be broken, but feel free to give it a try.

GrabCartoons is a comic-summarizing utility. It is modular, and it is very easy to write modules for new comics. It’s one of my oldest open-source projects, and still in use!
