 I am not really that familiar with it. Someone mentioned that it was
make implemented in erlang some time ago and I assumed it was true. As
to its limitations I couldn't tell you.

 It does build files thats true. However, I wouldn't classify that as
a build system. That said if you use erlide it will happily build the
files that are part of your project.

 This is a conversion that Martin and I have spent a lot of time on.
In the end it comes down to your preference. erlware has the concept
of a central build area for all of your erlang projects. Its also
built around make and shell scripts. Erlware has a very unixy feel
that many may find appealing. Sinan does a per project or per
application build (though the dependency repo is shared). Sinan is
written and extensible in Erlang. If anything Sinan feels like a much
smarter version of java's ant then anything else. They both understand
and require OTP infrastructure in the projects that they are capable
of building. They both use the same repository format. They both are
capable of generating 'getting started' project templates that are
buildable from the get go. There are a lot of similarities between the
two in output. However, they approach the problem of building otp apps
very differently. I don't believe that one is intrinsically superior
then the other, its just a matter of which you are more comfortable
