+===== PART 8: Merge back to trunk =====
+After the conflict is resolved and committed from branch, go back to trunk
+<file>
+alfg@pc4400:~/twoDevelopers/trunk$ svn update
+alfg@pc4400:~/twoDevelopers/trunk$ svn merge --reintegrate file://$HOME/svnrepos/testproject/branches/aBranch
+</file>
+AT THIS POINT YOU WANT TO PASS THE TESTS (IF THIS WAS NORESM)
+<file>
+alfg@pc4400:~/twoDevelopers/trunk$ svn commit -m "merged aBranch back to trunk"
+</file>
+==> Observe that you don't get any conflict this time. Svn knows that the conflict is already resolved.
+===== Other important points =====
+  * The merge is not completed until you commit!
+  * You have to know if you are doing a reintegrate merge or a merge from trunk (see noresm wiki)
+  * You can undo the merge with alfg@pc4400:~/twoDevelopers/aBranch$ svn revert -R .
+  * When you have done a "reintegrate merge", consider  your branch dead! (svn delete branchUrl -m "removed reintegrated branch aBranch")
+  * If you insist on keeping reintegrated branches alive, there are two options:
+      - Start using another version control system
+      - Make sure you have latest svn version (version >= 1.7), Then read (and understand)  http://svnbook.red-bean.com/en/1.7/svn.branchmerge.advanced.html#svn.branchmerge.advanced.reintegratetwice
