DESCRIPTION
-----------
Set the path to the repository. This can also be controlled by
setting the GIT_DIR environment variable.
+--work-tree=<path>::
+ Set the path to the working tree. The value will not be
+ used in combination with repositories found automatically in
+ a .git directory (i.e. $GIT_DIR is not set).
+ This can also be controlled by setting the GIT_WORK_TREE
+ environment variable and the core.worktree configuration
+ variable.
+
--bare::
Same as --git-dir=`pwd`.
specifies a path to use instead of the default `.git`
for the base of the repository.
+'GIT_WORK_TREE'::
+ Set the path to the working tree. The value will not be
+ used in combination with repositories found automatically in
+ a .git directory (i.e. $GIT_DIR is not set).
+ This can also be controlled by the '--work-tree' command line
+ option and the core.worktree configuration variable.
