+The feed icon isn't so easy to create with TikZ (I don't know the necessary parameters), so I downloaed one (256x256) from `IconFinder <https://www.iconfinder.com/icons/49861/feed_rss_icon>`_. The original PNG can be found `here <http://i.imgur.com/4XE3iL3.png>`_. Then I processed the PNG with ``optipng``, the result of which is ``feed-256.png``. The smaller ``feed-14.png`` is generated through::

 My first programming language was Pascal and I consider C my mother tongue, but recently I write my code in Python or Bash (non-interactive) most of the time. My operating system is OS X, my text editor is Emacs, my interactive shell is Zsh, my package manager is Homebrew, and my default browser (at the moment — it changes a lot) is Google Chrome. I use four-space indents. What else is there to tell?
