No content yet other than man pages. To make the man pages render
nicely in mkdocs, I removed the static %-headers and put the code for
them into default.md.tmp.do instead. That way, the raw input redo-*.md
files will look right in mkdocs.
We have to go through some pretty scary gyrations to extract this
information from git, but it can be done. This works with both tarballs
generated by 'git archive', or with your local git repo.
