   ghellopcb.c -o ghellopcb.so `pkg-config --cflags gtk+-2.0 --libs gtk+-2.0`
 * \n\n
 * The resulting ghellopcb.so file should go in $HOME/.pcb/plugins/\n
 * \n
 * \warning Be very strict in compiling this plug-in against the exact pcb
 * sources you compiled/installed the pcb executable (i.e. src/pcb) with.\n
