- * "git fast-rebase" builtin command
- *
- * FAST: Forking Any Subprocesses (is) Taboo
- *
- * This is meant SOLELY as a demo of what is possible. sequencer.c and
- * rebase.c should be refactored to use the ideas here, rather than attempting
- * to extend this file to replace those (unless Phillip or Dscho say that
- * refactoring is too hard and we need a clean slate, but I'm guessing that
- * refactoring is the better route).
