 +If you are like me then it is possible that you have forgotten what the parent of your task branch is.  In this case the command
 +<code>
 +svn log --stop-on-copy --verbose | tail -n 20

 So, let's merge the changes from the trunk (in this example!) into your task branch.

 A merge conflict can occur when two or more people make different changes to the same file. When Subversion encounters a merge conflict (e.g. during an update), it will place specific markers in the original source file.  A merge conflict can occur when two or more people make different changes to the same file.
