• Install from npm (npm install -g @dekit/cli) or PyPI
  (pip install dekit-cli)
• The console groups tasks by path: web/api and web/ui sit under a
  web/ group that collapses and expands with <h> and <l>
• dekit ls and the console list tasks in the order of dekit.yaml
• q in the console asks how to quit: q down, x quit without saving,
  d detach
• dekit with no command starts the runner like dekit up when it is not
  running
• A binary started as mprocs (through a link) runs dekit mprocs
• dekit update updates only a dekit from the install script; for other
  installs it says to update that way
