Does anyone know of a good line of code (LOC) counter that supports several different programming languages?

I'd like to add some basic metrics to our daily build system, but covering source code written in Java, JSP, JavaScript, PL/SQL and XSL.

Ideally I need such a tool to have a Ant integration, although if it's cross-platform then I could execute it.

The only ones I've found so far are Java-specific (LOCC etc), or not cross platform (e.g. SLOCC).
