To compile GAMGI, check the library paths in $GAMGI/src/make_local and type make, as described in the file $GAMGI/INSTALL. If problems arise, see: http://www.gamgi.org/documentation/install.html.

To start GAMGI, type gamgi in a terminal. To see how GAMGI works, press Help on the window. To see how GAMGI Help works, select Help->Topic->Help on the window.

Unless stated otherwise, $GAMGI represents the actual GAMGI root directory, for example /opt/gamgi, /usr/local/gamgi or /home/carlos/gamgi/gamgi0.11.11.

GAMGI source code is in the directory $GAMGI/src, distributed over the sub-directories engine, gtk, mesa, math, chem, phys, io, expat and global.

To understand GAMGI control flow, the first file to check is $GAMGI/src/global/gamgi_global_main.c, where GAMGI starts and ends. To understand GAMGI data flow, the first file to check is $GAMGI/src/engine/gamgi_engine.h, which contains the primary data types and definitions.

Each .c file has a corresponding .h file and each directory has a general .h file. All local functions start with the name static and all global functions start with the name of the file containing them. All functions in a .c file are listed in the corresponding .h file, including local (commented) functions and argument names, plus a rationale describing the control flow. GAMGI has one (redundant) global variable, called gamgi.

Unless stated otherwise, $GAMGI represents the actual GAMGI root directory, for example /opt/gamgi, /usr/local/gamgi or /home/carlos/gamgi/gamgi0.11.11.
