A few notes: * The methods to call (*self.meths*) can be specified dynamically (removing, adding, ..) * The 'features' are used to add methods to self.meths and then execute them * The attribute 'path' is a node representing the location of the task generator * The tasks created are added to the attribute *tasks* * The attribute 'idx' is a counter of task generators in the same path cOs(g|_d|_g|_g|_g|_d|vr>t|_d|_d|_n|d|_ |j j |_| d|j j|_|j }z&|j j |dd|_|j j|<Wn,t yi|j _d|_|j j|<Yn0z|j jd|_|j _Wn"t yd|_|j _Yn0|D]\}}t|||q dS)a Task generator objects predefine various attributes (source, target) for possible processing by process_rule (make-like rules) or process_source (extensions, misc methods) Tasks are stored on the attribute 'tasks'.
