GLISSANDO is a Glauber Monte-Carlo generator for early-stages of relativistic heavy-ion collisions, written in c++ and interfaced to ROOT. Several models are implemented: the wounded-nucleon model, the binary collisions model, the mixed model, and the model with hot-spots. The original geometric distribution of sources (i.e., wounded nucleons or binary collisions) in the transverse plane can be superimposed with a statistical distribution simulating the dispersion in the generated transverse energy in each individual collision. The program generates inter alia the fixed axes (standard) and variable-axes (participant) two-dimensional profiles of the density of sources in the transverse plane and their Fourier components. These profiles can be used in further analyses of physical phenomena, such as the the jet quenching, event-by-event hydrodynamics, or analyses of the elliptic flow and its fluctuations. Characteristics of the event (multiplicities, eccentricities, Fourier shape coefficients, etc.) are evaluated and stored in a ROOT file for further off-line studies. A number of scripts is provided for that purpose. The code can also be used for the proton-nucleus and deuteron-nucleus collisions.

Version 2 of GLISSANDO offers much more functionality than version 1, moreover, it is fully object-oriented, providing the user with the flexibility of inspecting and, if needed, modyfying the code in a simple manner. New features involve:
