I believe that under 1.8 it comes as its own class, but in 1.9 on it
is the code behind the builtin Regexp class. (I could be wrong,
though. There may be a way to build 1.8 using Oniguruma as the basis
for Regexp.)

And, from what I know, all regex features available in 1.8 use the
same syntax in Oniguruma.
