Previously I have used freshrc to manage my dotfiles (the history of which
is in the shell subtree). It was too complicated. Then I switched to a
combination of vcsh and myrepos, which added a lot of overhead.
Specifically, I did not like that the files didn't exist in a Git repository,
which broke VCS integration with my editors. After an erroneous
git fetch was auto-corrected to
vcsh foreach init and broke my local repos,
I realized I needed just one repo.
