Gerbv is a viewer for Gerber RS-274X files, Excellon drill files, and CSV
pick-and-place files. (Note: RS-274D files are not supported.)
The core functionality of gerbv is located in a separate library
(libgerbv), allowing developers to include Gerber
parsing/editing/exporting/rendering into other programs.
