 This section describes the process to update a submodule when a new version of a library has been released upstream.
-The examples given here are for the ADOdb library, but the same logic should apply (possibly with some variations) to other submodules as well.

+The example given here are for the ADOdb library, but the same logic should apply (possibly with some variations) to other submodules as well.
 We assume that you already have a local repository configured with the appropriate remotes (//upstream// for the library's official repository and //origin// for the MantisBT fork)

+==== Updating from within the submodule ====
+It's worth mentioning that step 1 above can also be performed straight from the submodule itself (see example below for phpmailer), provided of course that the remotes (origin and upstream) have been properly configured.
+**WARNING**: if you update the submodule in-place, it is critical that you actually push the changes to //origin// otherwise the other developers will have an corrupted repository with missing commits when they pull the changes.
+  * Update the submodule from upstream <code>
+cd library/phpmailer
+git fetch upstream
+git rebase upstream/master master
+git checkout mantis
+git merge v5.2.7
+# Resolve conflicts
+</code>
+  * Push changes to the fork - **don't forget this step !**<code>
+git push origin --tags master mantis
+cd ..
+</code>
+  * Edit ''README.libs''
+  * Commit the changes <code>
+git commit -a
