关于Express 3.* EJS include 的疑问

一开始这样写
var html = ejs.render(tmp, {user:{name:'test'});
ejs模板是这样的：
<html>
<head>
<% include head.ejs %>
</head>
<body>
<% include top_bar.ejs %>
<h1><%=user.name %></h1>
<ul>
<li>11111</li>
<li>22222</li>
<li>33333</li>
<li>44444</li>
</ul>
<% include foot.ejs %>
</body>
</html>
结果控制台报错：
Error: filename option is required for includes
然后去看github上的API发现有个filename参数，试着改成
var html = ejs.render(tmp, {user:{name:'test'},filename:"ejs/head.ejs"});
结果居然正常了！？？问题是我模板文件里include的3个文件，为什么参数里只写了一个就行了呢？ API里这段话没看懂，求大家指点一二：
Includes are relative to the template with the include statement, for example if you have "./views/users.ejs" and "./views/user/show.ejs" you would use <% include user/show %>. The included file(s) are literally included into the template, no IO is performed after compilation, thus local variables are available to these included templates.
