       "Generates a command sequence which copies the name texts "
       "of all elements of your layout into newly generated layers (125 and 126). "
       "After running the ULP you can GROUP, CUT and PASTE your layout "
       "to get an array of several boards. Make sure all layers are displayed before."
       "<p>"
       "The duplicated name texts in the new layers will not be changed. "
       "Please notice that you have to deactivate layers 25 and 26 if you use "
       "the CAM processor e.g. for generating gerber data. Instead, you have to activate "
       "the new layers 125 and 126. Thus you get an identical silk screen for all "
       "your layouts in this array."
