Arpeggio is implemented using or influenced by the following free/libre
technologies:

- [Python Programming Language](http://www.python.org)
- [PyPEG v1.x](http://fdik.org/pyPEG/) and
  [pyparsing](http://pyparsing.wikispaces.com/) for ideas and inspiration.

Although not directly related to Arpeggio I wish also to thank to the following
free software projects that makes the development of Arpeggio (and some other
projects I am working on) easier and more fun:

- [Arch Linux](http://www.archlinux.org/) - A fantastic Linux distro for sw
  development
- [Emacs editor](https://www.gnu.org/software/emacs/) - An extensible,
  customizable, free/libre text editor — and more
  - ... and [spacemacs
    distribution](http://www.igordejanovic.net/2016/11/08/my-spacemacs-odyssey.html) -
    A beautiful Emacs distribution
- [Vim editor](http://www.vim.org/) - The power tool for everyone!
- [Git](http://git-scm.com/) - Distributed version control system

... and many more
