What is erb and gerb?

ERB stands for Embedded Ruby, which is a templating system for Ruby programmers. It allows developers to embed Ruby code in HTML documents, so that the code can be executed dynamically. This enables developers to generate dynamic web pages quickly and easily.

Gerb is a file format used in the manufacturing of printed circuit boards (PCBs). Gerber files specify the layout of the circuit board and provide instructions for the manufacturing equipment. Each layer of the PCB is represented by a separate Gerber file, including copper layers, silkscreen layers, and drill holes. Gerber files are generated by PCB design software and are used by manufacturers to create the final product.
