+ NAME
+ ----
+-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>
