Github support for org-mode in READMEs is unsatisfying - no code coloring and sometimes
it even fails to render to html at all.
I am migrating all my README files to markdown.
Googled also this tool for automatic conversion: https://github.com/alexhenning/ORGMODE-Markdown.
Will try it next time.
Apart from READMEs I also would like to represent TODO.org files online. While org -formatted
READMEs are more or less readable in gitbub's HTML representations, TODO.org files
are not readable at all.
