One more remark: If possible, you should use some kind of version
control system, such as CVS or SVN. And if this is not part of your
working infrastructure, you should set up one on your local machine.
Sometimes it just happens that you forget to change a @generated tag to
@generated NOT, which can not only cost you hours of work, but worse:
you will most likely not even notice that the code has been overwritten,
at least not immediately. Synchronizing your projects with a SVN, e.g.
using Subclipse, you can see which files have been changed, and how,
when regenerating the code.

Tobias,
It's good advice because it's scary to work without version control.
The merging generator is nice because it only overwrites files that
actually change, so when you regenerate, you can determine exactly
what's been touched and needs to be checked in.
Martin,
Another good pattern to use, when possible, is to rename a method foo,
to fooGen and then call fooGen for your specialized foo method. This
way fooGen will still be regenerated and your override of it will be
preserved. It's effectively like creating a derived class and putting
your override in there...
