+Valeur automatiquement modifiée
+===============================
+
+Une variable avec valeur automatiquement modifiée est une variable dont la valeur sera considéré comme modifié quand le serveur sera déployé.
+
+Voici un variable a valeur automatiquement modifiée :
+
+    <variable name="my_variable" type="oui/non" description="My variable" auto_save="True">
+
+Dans ce cas la valeur est fixée à la valeur actuelle.
+Par exemple, si la valeur de cette variable est issue d'un calcul, la valeur ne sera plus recalculée.

+Les variables calculées
+=======================
+
+Une variable calculée est une variable donc sa valeur est le résultat d'une fonction python.
+
+Variable avec une valeur par défaut calculée
+--------------------------------------------
+
+Créons une variable de type "oui/non" donc la valeur est retournée par la fonction "return_no" :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" type="oui/non" description="My calculated variable"/>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_no" target="my_calculated_variable"/>
+    </constraints>
+
+Puis créons la fonction "return_no" :
+
+    def return_no():
+        return 'non'
+
+Dans ce cas, la valeur par défaut est la valeur retournée par la fonction (ici "non"), elle sera calculée tant que l'utilisateur n'a pas de spécifié une valeur à cette variable.
+
+Si l'utilisateur à définit une valeur par défaut à "my_calculated_variable" :
+
+    <variable name="my_calculated_variable" type="oui/non" description="My calculated variable">
+        <value>oui</value>
+    </variable>
+
+Cette valeur par défaut sera complètement ignorée.
+
+Variable avec une valeur calculée
+---------------------------------
+
+En ajoutant le paramètre "hidden" à "True" dans la variable précédente, l'utilisateur n'aura plus la possibilité de modifié la valeur. La valeur de la variable sera donc systématiquement calculée :
+
+    <variable name="my_calculated_variable" type="oui/non" description="My calculated variable" hidden="True"/>
+
+Si une condition "hidden_if_in" est spécifié à la variable, la valeur sera modifiable par l'utilisateur si elle n'est pas cachée mais elle sera systèmatiquement calculée (même si elle a déjà était modifiée) si la variable est cachée.
+
+Variable avec valeur calculée obligatoire
+-----------------------------------------
+
+Par défaut les variables calculées ne sont pas des varibles obligatoires.
+Dans ce cas un calcul peut retourner None, mais surtout un utilisateur peut spécifier une valeur nulle à cette variable. Dans ce cas le calcul ne sera pas réalisé.
+
+Fonction avec une valeur fixe comme paramètre positionnel
+---------------------------------------------------------
+
+Déclarons un calcul avec paramètre :
+
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable">
+            <param>non</param>
+        </fill>
+    </constraints>
+
+Créons la fonction correspondante :
+
+    def return_value(value):
+        return value
+
+La variable aura donc "non" comme valeur puisque le paramètre aura la valeur fixe "non".
+
+Paramètre nommée
+----------------
+
+Déclarons une contrainte avec un paramètre nommée :
+
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable">
+            <param name="valeur">non</param>
+        </fill>
+    </constraints>
+
+Dans ce cas la fonction return_value sera exécuté avec le paramètre nommé "valeur" dont sa valeur sera "non".
+
+Paramètre avec un nombre
+------------------------
+
+Déclarons un calcul avec paramètre avec un nombre :
+
+    <constraints>
+        <fill name="return_value_with_number" target="my_calculated_variable">
+            <param type="number">1</param>
+        </fill>
+    </constraints>
+
+Créons la fonction correspondante :
+
+    def return_value_with_number(value):
+        if value == 1:
+            return 'non'
+        return 'oui'
+
+La variable aura donc "non" comme valeur puisque le paramètre aura la valeur fixe "1".
+
+Paramètre dont la valeur est issue d'une autre variable
+-------------------------------------------------------
+
+Créons deux variables avec une contrainte de type variable qui contient le nom de la variable dont sa valeur sera utilisé comme paramètre :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" type="oui/non" description="My calculated variable"/>
+            <variable name="my_variable" type="number" description="My variable">
+                <value>1</value>
+            </variable>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_value_with_number" target="my_calculated_variable">
+            <param type="variable">my_variable</param>
+        </fill>
+    </constraints>
+
+Si l'utilisateur laisse la valeur 1 à "my_variable", la valeur par défault de la variable "my_calculated_variable" sera "non".
+Si la valeur de "my_variable" est différent de 1, la valeur par défaut de la variable "my_calculated_variable" sera "oui".
+
+Paramètre dont la valeur est issue d'une information de la configuration
+------------------------------------------------------------------------
+
+Créons une variable et la contrainte :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" type="string" description="My calculated variable"/>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable">
+            <param type="information">server_name</param>
+        </fill>
+    </constraints>
+
+Dans ce cas, l'information de la configuration "server_name" sera utilisé comme valeur de la variable "my_calculated_variable".
+Si l'information n'existe pas, la paramètre aura la valeur "None".
+
+Paramètre avec variable potentiellement non existante
+-----------------------------------------------------
+
+Suivant le contexte une variable peut exister ou ne pas exister.
+
+Un paramètre de type "variable" peut être "optional" :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" type="oui/non" description="My calculated variable"/>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable">
+            <param type="variable" optional="True">unknow_variable</param>
+        </fill>
+    </constraints>
+
+Dans ce cas la fonction "return_value" est exécuté sans paramètre.

+
+Les variables dynamiques
+------------------------
+
+Paramètre avec variable dynamique
+'''''''''''''''''''''''''''''''''
+
+Il est possible de faire un calcul avec comme paramètre une variable dynamique mais pour une suffix particulier :
+
+    <variables>
+        <family name='family'>
+            <variable name='suffixes' type='string' description="Suffixes of dynamic family" multi="True">
+                <value>val1</value>
+                <value>val2</value>
+            </variable>
+            <variable name="my_calculated_variable" type="string" description="My calculated variable"/>
+        </family>
+        <family name='dyn' dynamic="suffixes">
+            <variable name='vardyn' type='string' description="Dynamic variable">
+                <value>val</value>
+            </variable>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable">
+            <param type="variable">vardynval1</param>
+        </fill>
+    </constraints>
+
+Dans ce cas, valeur du paramètre de la fonction "return_value" sera la valeur de la variable "vardyn" avec le suffix "val1".
+
+Calcule d'une variable dynamique
+''''''''''''''''''''''''''''''''
+
+Il est également possible de calculer une variable dynamique à partir d'une variable standard :
+
+    <variables>
+        <family name='family'>
+            <variable name='suffixes' type='string' description="Suffixes of dynamic family" multi="True">
+                <value>val1</value>
+                <value>val2</value>
+            </variable>
+            <variable name="my_variable" type="string" description="My variable">
+                <value>val</value>
+            </variable>
+        </family>
+        <family name='dyn' dynamic="suffixes">
+            <variable name="my_calculated_variable_dyn_" type="string" description="My calculated variable"/>
+                <value>val</value>
+            </variable>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_value" target="my_calculated_variable_dyn_">
+            <param type="variable">my_variable</param>
+        </fill>
+    </constraints>
+
+Dans ce cas, les variables dynamiques "my_calculated_variable_dyn_" seront calculés à partir de la valeur de la variable "my_variable".
+Que cela soit pour la variable "my_calculated_variable_dyn_val1" et "my_calculated_variable_dyn_val2".
+
+Par contre, il n'est pas possible de faire un calcul pour une seule des deux variables issues de la variable dynamique.
+Si c'est ce que vous cherchez à faire, il faudra prévoir un traitement particulier dans votre fonction.
+
+Dans ce cas, il faut explicitement demander la valeur du suffix dans la fonction :
+
+    <constraints>
+        <fill name="return_value_suffix" target="my_calculated_variable_dyn_">
+            <param type="variable">my_variable</param>
+            <param type="suffix"/>
+        </fill>
+    </constraints>
+
+Et ainsi faire un traitement spécifique pour ce suffix :
+
+    def return_value_suffix(value, suffix):
+        if suffix == 'val1':
+            return value
+
+Redéfinition des calcules
+-------------------------
+
+Dans un premier dictionnaire déclarons notre variable et notre calcule :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" type="oui/non" description="My calculated variable"/>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_no" target="my_calculated_variable"/>
+    </constraints>
+
+Dans un second dictionnaire il est possible de redéfinir le calcul :
+
+    <variables>
+        <family name="family">
+            <variable name="my_calculated_variable" redefine="True"/>
+        </family>
+    </variables>
+    <constraints>
+        <fill name="return_yes" target="my_calculated_variable"/>
+    </constraints>
+
+Dans ce cas, à aucun moment la fonction "return_no" ne sera exécuté. Seul la fonction "return_yes" le sera.
