   8 # A few rules for repo setup:
   9 #
  10 # 1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
  11 #    GIT_DIR.
  12 #
  13 # 2. .git file is relative to parent directory. .git file is basically
  14 #    symlink in disguise. The directory where .git file points to will
  15 #    become new git_dir.
  16 #
  17 # 3. core.worktree is relative to git_dir.
  18 #
  19 # 4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
  20 #    equivalent to GIT_WORK_TREE.
  21 #
  22 # 5. GIT_WORK_TREE/core.worktree is only effective if GIT_DIR is set
  23 #    Uneffective worktree settings should be warned.
  24 #
  25 # 6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
  26 #
  27 # 7. Effective core.worktree conflicts with core.bare
  28 #
  29 # 8. If GIT_DIR is set but neither worktree nor bare setting is given,
  30 #    original cwd becomes worktree.
  31 #
  32 # 9. If .git discovery is done inside a repo, the repo becomes a bare
  33 #    repo. .git discovery is performed if GIT_DIR is not set.
  34 #
  35 # 10. If no worktree is available, cwd remains unchanged, prefix is
  36 #     NULL.
  37 #
  38 # 11. When user's cwd is outside worktree, cwd remains unchanged,
  39 #     prefix is NULL.
