Matt,

"Gerber" was originally a photoplotter format. The photoplotter had a
"wheel" or disk with the shapes around the circumference. Think photo
negatives of geometric shapes. Each wheel had a file with the corresponding
shapes with their position on the wheel.

In the older gerber formats, the wheel file was separate, in the newer
gerber format, it is included.

Of course, today the photoplotter was replacedd by software.
