RoR uses something rather than erb or eRuby?

the program erb and the description of eRuby at

http://www.eruby.info

both said that

<% print "foo bar" %> or <% puts "hello" %>

They go into STDOUT, hence out your program. They don't put anything
into the returned string. Only <%= ... %> does that.

So, yes RoR definitely uses eRB.
