+ <para>Since GateIn beta 2, we added a set of features in order to
+ customize a GateIn instance without modifying the GateIn binary, this

+ several portal instances at the same time, in "eXo terminology" that

+ <title>Motivations</title>
+
+ <para>Up to now, to create an application over an eXo portal such as
+ DMS, WCM, CS and KS, we need to modify files into the "portal.war". This
+ has many painful consequences, such as:</para>
+
+ <itemizedlist>
+ <listitem>
+ <para>It is quite hard to manage from the support point of view
+ since we never know if or how the customer changed his eXo
+ product.</para>
+ </listitem>
+
+ <listitem>
+ <para>It is hard to be able to package several eXo products (WCM,
+ CS...) as we need to merge everything manually which is quite error
+ prone.</para>
+ </listitem>
+ </itemizedlist>
+
+ <para>Finally, at the very beginning, eXo was developed to be able to
+ support several portal instances (which also means several portal
+ containers) but with the time several bad practices made it impossible.
+ So it was important to review the whole code base in order to
+ help/enforce all the GateIn developers to follow the "good
+ practices".</para>
