+ <p>This example demonstrates the libgit2 index APIs to roughly
+simulate the output of <code>git ls-files</code>.
+<code>git ls-files</code> has many options and this currently does not show them.</p>
+
+<p><code>git ls-files</code> base command shows all paths in the index at that time.
+This includes staged and committed files, but unstaged files will not display.</p>
+
+<p>This currently supports the default behavior and the <code>--error-unmatch</code> option.</p>
