+   in \ref m_host_management (only the read-only functions i.e. whose

+   or destroy some #m_task_t for example) and in \ref
+   msg_gos_functions (to handle file transfers and task processing).
+ * \param data a pointer to any data one may want to attach to the new
+   object.  It is for user-level information and can be NULL. It can
+   be retrieved with the function \ref MSG_process_get_data.
+ * \param host the location where the new agent is executed.
+ * \param argc first argument passed to \a code
+ * \param argv second argument passed to \a code
+ * \param properties list a properties defined for this process
