--git-ls-tree - Displays a tree object in human readable form
-+git-ls-tree - Lists the contents of a tree object.
- 
- 
- SYNOPSIS
- --------
--'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
-+'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
- 
- DESCRIPTION
- -----------
--Converts the tree object to a human readable (and script processable)
--form.
-+Lists the contents of a tree object, like what "/bin/ls -a" does
-+in the current working directory.
- 
- OPTIONS
- -------
- <tree-ish>::
- 	Id of a tree.
- 
-+-d::
-+	show only the named tree entry itself, not its children
-+
- -r::
- 	recurse into sub-trees
- 
-@@ -28,18 +31,19 @@ OPTIONS
- 	\0 line termination on output
- 
- paths::
--	Optionally, restrict the output of git-ls-tree to specific
--	paths. Directories will only list their tree blob ids.
--	Implies -r.
-+	When paths are given, shows them.  Otherwise implicitly
-+	uses the root level of the tree as the sole path argument.
-+
- 
- Output Format
- -------------
--        <mode>\t	<type>\t	<object>\t	<file>
-+        <mode> SP <type> SP <object> TAB <file>
