Blackberry Build Tool

Could anyone suggest the best Build Tools for use in the build pro开发者_C百科cess when building a blackberry application.

Is it just the creation of an ANT project, does that cope with signing etc?

Is there a better tool out there? I'd prefer a lightweight Windows solution.

I normally use Automated Build Studio -- it can build ANT and it can also compile Java.

I don't know of any serious alternative to bb-ant-tools.
