\chapter{Introduction} 

I suppose the real documentation is the source code, for such a manual,
the first pages would (of course) be the header files.   This manual is
not intended to fully document the code for the XWindows/Motif interface
for AGNI.  Instead, it is an introduction to the philosophy behind how
it is designed and an overview of its structure.  The best way to learn
the code is to hack on it.  There are comments throughout the sources,
the best of which are likely the function names (consequently, some
function names can get a rather long).
