### 1. What are GAMGI hardware requirements?

To run properly, GAMGI requires a graphics environment with with at least 16 bits per pixel, otherwise object selection with the mouse does not work, and using GAMGI becomes much more difficult.

GAMGI requires a 3-button mouse to work properly, as the mouse buttons are one of the ways to rotate, move and scale objects. With a 2-button mouse, users can configure the button order for example to discard scale and use move and rotate modes only.

### 2. What are GAMGI software requirements?

GAMGI can be installed on any computer running Linux/Unix with the standard X Window System. GAMGI requires the following libraries: Glib/Gtk, Mesa, Gtkglarea, Expat and Freetype.

GAMGI should run with any version of Glib/Gtk 1, but does not even compile with Glib/Gtk 2. GAMGI should run with any version of Mesa or OpenGL, though a recent release is recomended, due to some bugs. GAMGI should run with any version of Gtkglarea 1. GAMGI should run with any version of Expat. GAMGI should run with any version of Freetype 2, but does not even compile with Freetype 1.
