# 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.
