+=================
+
+NAME
+----
+git-diff-files - Compares files in the working tree and the index
+
+
+SYNOPSIS
+--------
+[verse]
+'git diff-files' [-q] [-0 | -1 | -2 | -3 | -c | --cc] [<common-diff-options>] [<path>...]
+
+DESCRIPTION
+-----------
+Compares the files in the working tree and the index.  When paths
+are specified, compares only those named paths.  Otherwise all
+entries in the index are compared.  The output format is the
+same as for 'git diff-index' and 'git diff-tree'.
+
+OPTIONS
+-------
+include::diff-options.adoc[]
+
+-1 --base::
+-2 --ours::
+-3 --theirs::
+-0::
+	Diff against the "base" version, "our branch", or "their
+	branch" respectively.  With these options, diffs for
+	merged entries are not shown.
++
+The default is to diff against our branch (-2) and the
+cleanly resolved paths.  The option -0 can be given to
+omit diff output for unmerged entries and just show "Unmerged".
+
+-c::
+--cc::
+	This compares stage 2 (our branch), stage 3 (their
+	branch), and the working tree file and outputs a combined
+	diff, similar to the way 'diff-tree' shows a merge
+	commit with these flags.
+
+-q::
+	Remain silent even for nonexistent files
