# Don't refresh index/config/etc before doing checkout.
#

# Treat pathspec as simple list of exact match file paths.

# Allow checkout to skip unmerged files (NOT IMPLEMENTED).
#

# :dirty ::
# Invoke the callback for "dirty" files, i.e. those that do not need
# an update but no longer match the baseline.
#
# :updated ::
# Invoke the callback for any file that was changed.
#
# :untracked ::
# Invoke the callback for untracked files.
#
# :ignored ::
# Invoke the callback for ignored files.

# :all ::
# Invoke the callback for all these cases.
