Gerbers are a version of G-CODE Data Format commonly used in the manufacture of PCBs.
From a sample file, we can see the definition of a series of "apatures" with the %ADD command, followed by a number (must be 10 or higher) then a shape letter, comma, size, etc... The shapes are:
%ADD15R,0.080X0.013*% %ADD16C,0.013*% %ADD17C,0.015*% %ADD18C,0.008*% %ADD19C,0.010*% %ADD20C,0.005*% %ADD21O,0.075X0.065*%
Later in the file, the D15 command references the first line shown above, %ADD15R,0.080X0.013*% where a rectangle 0.08 by 0.013 inches is defined. It then move the location to 10.402, 8.651 using the X and Y letters and the D02 (move cursor) command. On the next line, the D03 command exposes the D15 appature at that location.
D15* X10402Y8651D02* D03*
Appatures can also be used to draw lines. Here, the D16 appature is used at a starting point set with the D02 command, but then it is "stroked" to the next point via the D01 command.
D16* X10464Y8680D02* X10509Y8726D01* X10464Y8645D02* Y8680D01*
