/*------------------------------------------------------------------------------
       Filename: example1.c
       
       Description: Loads example1-input.gbx into a project, and then exports
              the layer back to another RS274X file.

       Instructions: Make sure you are in the example-code directory, and compile
              this program with the following command:

       gcc -Wall -g `pkg-config --cflags libgerbv` `pkg-config --libs libgerbv` example1.c -o example1

       Run with the following command:
       
       ./example1
       
       Common compiling problems:
              1. If you are compiling gerbv from source, make sure you run
                     "make install" before trying to compile this example. This
                     ensures libgerbv is correctly installed and can be found.
              2. If you installed gerbv to "/usr/local" (the default), many
                     distributions don't correctly point pkgconfig to this target.
                     To fix this, add the following to your ~/.bashrc file:
                     
                     export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:/usr/lib/pkgconfig/
