in HAML what does {%= %} mean?

Question

I see this line in a .html.haml file (RoR project)

.upload
  {%=o.name%}

What does it mean? it just prints the output of o.name? I mean, it is the same than:

.upload
  =o.name

Or does a funky parse.

Thanks!

我怀疑这是HAML语法的一部分，因此它可能在客户端站点上用于模板化或其他目的（如Stefan所提到的）。
