Wayne,

Thanks for your helpful replies.
However, I don't understand well you last comment (rsync only deletes in 
directories that it sends).

Consider that I want to transfer:
sparc/
	rel-1.0/
		file.c
		file.h
x86/	rel-1.0/
		file.c
		file.h

If I use: rsync -vaR */rel-1.0 /tmp/test-rsync/
I get:
sparc/
sparc/rel-1.0/
sparc/rel-1.0/file.c
sparc/rel-1.0/file.h
x86/
x86/rel-1.0/
x86/rel-1.0/file.c
x86/rel-1.0/file.h

Now, if I decide I want to remove the *.c files,
rsync -aRnv --exclude="*.c" --delete-excluded */rel-1.0 /tmp/test-rsync/
says:
deleting sparc/rel-1.0/file.c
deleting x86/rel-1.0/file.c

So, if I decide I want to remove rel-1.0 instead, I intended to use
rsync -aRnv --exclude="rel-1.0" --delete-excluded */rel-1.0 /tmp/test-rsync/

which does not work.

Why is the 2nd case different from the 1st one?

Christophe.
