Steping back from applied patch

Question

When creating a patch with the "patch" tool or with the built in "patch"-functionality in svn and then applying it to a source tree, is there any way to easily step back from the applied patch to the previous version?

Answer 1

svn revert? You can revert to the previous revision (before the patch was applied).

Answer 2

Apply the patch again in reverse (for example patch -R switch).
