Oh, maybe a few words about installation are in order. To compile and link the 'xbibfile' executable, you will need a C compiler and libraries, together with a GTK version 2.0 or greater graphics library. Basically one executable will be generated that can be stored where ever you desire. Because there are a number of sources files involved, a 'Makefile' is provided. Thus on a Unix or Linux system: make ./xbibfile & and you are away.
