# TODO: This hack makes a "plain" Markdown version of README.md that can be
# reasonably shipped as documentation file, while the current README.md is
# definitely intended for web browser consumption. It should probably work the
# other way around: the web version should be obtained by adding HTML and
# JavaScript portions to a plain Markdown, instead. However, cgit needs to use
# a file in the git tree. Find a better way around this.
