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