* Development
  This comes with a self-contained redo toolchain to help in working with the
  flake. It basically deploys any input flake into the =tmp= directory for easier
  access.

  redo targets under =tmp/= come in three kinds:
  - =clean= :: will remove all build products under =tmp/=
  - =<flake>= :: will make sure a store path to =<flake>= exists and puts an
    indirect root into =tmp/<flake>=.
  - =<flake>.rw= :: will make sure a store path to =<flake>= exists and will
    copy its contents to =tmp/.<flake>.rw= and will link to it from
    =tmp/<flake>.rw=. (Rationale: On Linux, directories cannot denote reliable
    targets due to their non-trivial relation to modification time.)
