# - If git.index.util *is* what you want, use (or import from) that, to avoid

# confusion.

# - To use the "real" git.util module, write `from git.util import ...`, or if

# necessary access it as `sys.modules["git.util"]`.

# Note also that `import git.util` technically imports the "real" git.util... but

# the *expression* `git.util` after doing so is still git.index.util!

# (This situation differs from that of other indirect-submodule imports that are

# unambiguously non-public and subject to immediate removal. Here, the public

# git.util module, though different, makes less discoverable that the expression

# `git.util` refers to a non-public attribute of the git module.)

# This had originally come about by a wildcard import. Now that all intended imports

# are explicit, the intuitive but potentially incompatible binding occurs due to the

# usual rules for Python submodule bindings. So for now we replace that binding with

# git.index.util, delete that, and let __getattr__ handle it and issue a warning.

# For the same runtime behavior, it would be enough to forgo importing util, and

# delete util as created naturally; __getattr__ would behave the same. But type

# checkers would not know what util refers to when accessed as an attribute of git.

The `path` parameter is usually omitted and cannot be used to specify a custom

command whose location is looked up in a path search on each call. See

This calls :meth:`Git.refresh <git.cmd.Git.refresh>` and sets other global

usually be used instead of using :meth:`Git.refresh <git.cmd.Git.refresh>` or

:meth:`FetchInfo.refresh <git.remote.FetchInfo.refresh>` directly.

This function is called automatically, with no arguments, at import time.
