This is GN version 2.08. Fairly extensive documentation is in the docs directory. I recommend that you at least skim the document "Install" in that directory. It explains how to compile GN, but more importantly how to use it. Before compiling you will need to edit the file "config.h" to put in appropriate values of things like your Operating System type and you root directory. You will also need to edit the Makefile. Unfortunately, I do not have time to answer all the questions sent to me by GN users. I recommend that you subscribe to the mailing list of gn maintainers and ask your questions there. It is read by many knowledgable GN users (including me). To subscribe with the address you're sending mail from, send a message to 'majordomo@hmc.edu', with "subscribe gn-maint-l" as the entire body (not the Subject: line) of the messge. To subscribe with some other address, do exactly as above, except use "subscribe gn-maint-l otheraddress" as the body, where "otheraddress" is the other address. (This second method requires the list maintainer's approval before it will take effect.) The people reading this list seem to be very helpful. John Franks Dept of Math.
