       Filename: example5.c
       
       Description: Demonstrate the basic drawing functions available in libgerbv
              by drawing a smiley face and exporting the layer to a new 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` example5.c -o example5
 
       Run with the following command:
       
       ./example5
       
       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/
