  * @section DESCRIPTION
  * 
  * Synopsis: call(string template_name, list args)
+ * 
  * Description:
  *   Module which allows using a single statement to represent multiple statements
  *   in a process template, allowing reuse of repetitive code.
  * 
- *   Behavior in detail:
+ * Variables:
+ *   Exposes variables as seen from the end of the called process template.
+ * 
+ * Behavior in detail:
  *   - On initialization, creates a new process from the template named
  *     template_name, with arguments args.
  *   - When all the statements in the created process go UP, transitions UP.
