+ SIMDAG:
+ * Add a new loader (SD_PTG_dotload) that creates a parallel task graph
+ (i.e., a DAG whose nodes are parallel tasks) from a dot file. Creates a
+ dynar of SD_TASK_COMP_PAR_AMDAHL and SD_TASK_COMM_MXN_1D_BLOCK tasks.
+ * Bug fix: let task be scheduled when the last dependency to be solved is
+ a control dependency.
+ * Remove SD_load_environment_script function.
+ Use the C sg_platf function if you want to declare a platform
+ programmatically.
