svn merge --dry-run -r:73:68 http://my.repository.com/my/project/trunk
svn merge -r:73:68 http://my.repository.com/my/project/trunk
svn commit -m "Reverted to revision 68."


# Explanation
#Step 1 will perform a dry run and show you what the merge will produce. If you want to see exactly what changes will be applied, do a diff:
#
# svn diff -r:73:68 http://my.repository.com/my/project/trunk

# create patch from diff between remote revisions
svn diff -r OLD:NEW > ~/changes_file.diff

# create patch from diff based on local changes
svn diff > ~/changes_file.diff

# apply a patch: -p0 makes sure that all files can be found correctly, -i specifies the input diff file
patch -p0 -i ~/changes_file.diff
