Consider the following problem:  a program comprised of  two major parts, one 
of which is a library linked against the main program's executable --- the 
other part.   Each of these parts has its own set of command-line options to 
be parsed at startup;  it is desirable to process them separately so that 
main program knows nothing about library module's options and vice versa.
A good living example is a GTK application, where call to gtk_init(&argc, 
&argv) gets GTK-specific options and leaves application-specific ones.  So I 
need some way to parse two separately defined sets of options mixed in one 
command-line arguments array, in separately compiled object files.

Sorry, I found no term "section" in documentation for gengetopt having to do 
with gengetopt files.
