Inspired by the GCC wiki
appearing on gcc.gnu.org, I wrote a
short
how-to about using the new binary compatibility mode and the
libgcj database (aka caching jit) feature.

This is by far the simplest way to deploy existing applications
using gcj. It works for Eclipse, and this is how I tried out Derby
the other day. This is also the way we’re taking to get jonas to
work.
