README for gerbv
(This software is ALPHA)

Gerber Viewer (gerbv) is a viewer for Gerber files. Gerber files are generated from PCB CAD system and sent to PCB manufacturers as basis for the manufacturing process.

The different layers of the PCB are separated into different files. gerbv can load all files at the same time, though it can not show them at the same time. You have to browse through the different layers with the radio buttons on the right side.

System Requirements
gerbv is dependent on a couple of different external libraries:
- GTK+, the graphical toolkit available from http://www.gtk.org/
- GdkPixbuf (default but not necessary), extracts data from GDK pixbufs.
- libpng (default but not necessary), saves extracted pixbufs to PNG.
- getopt_long from the GNU project. gerbv can do without getopt_long long options to the program will hence not be available.

gerbv is basically known to compile on all system which the above mentioned libraries compile on, basically all flavors of ix. It has been tested on Linux (2.2., 2.4.*), NetBSD (1.4.*, 1.5.*), Solaris (5.7 and 5.8).

Scroll Wheel
gerbv supports zooming with scroll wheel. To be able to use scroll wheel in XFree86 3.x you have to edit XF86Config and add the line:
ZAxisMapping 4 5 in the Section "Pointer".
To use scrool wheel in XFree86 4.x you have to add the line:
Option "ZAxisMapping" "4 5" under the input device describing your mouse.
