The utils/ subtree is very similar in all aspects except that it is for external utility programs. Utils that are closely related to pcb-rnd, such -as gsch2pcb-rnd, should work from the same configuration (e.g. to -make sure the same footprint paths are searched). If they already load the +as gsch2pcb-rnd, should work from the same configuration. +If they already load the pcb-rnd config files it's easier to keep their settings in the same tree, in the same format.
