How to (re)generate patches from subversion commits?

Question

Let's imagine a series of commits have been performed on a branch, but the branch has not been resynchronized with trunk yet. Is it possible to generate global patches from a commit? Is it possible to generate a 'grouped' patch from a series of commits? If yes, how?

Answer 1

svn diff -rXXX:YYY URL > blah.patch

where XXX and YYY are the start and end revision numbers.
