    I nearly have the same problem :
    Sometimes we go and work in a customer site to make some bug fixing.
    We need to include in a jar all the classes that have changed since 
the last CVS update - and we don't have the access to CVS since we are 
not at home...
     The CVS client we use displays in red the changed files, but I 
don't know how to find them with Ant ?
    The idea to use the <copy> with the <different> selector is not to 
bad if we have a copy of the sources corresponding to the CVS 
repository. But maybe there is a better solution ?
    An Idea ?
