There was some discussion of this before, see
http://lists.wfu.edu/pipermail/gretl-users/2007-February/001310.html
and the following posts.

To update one suggestion there:

Cottrell, A, and Lucchetti, R. (2010) Gretl User's Manual,
http://sourceforge.net/projects/gretl/files/manual/

I investigate a little further and I think that according to ABNT (Brazilian National Standards Organization) we can use:

COTTREL, Allin; LUCCHETTI, Riccardo. Gretl: GNU Regression, Econometric and Time-series Library, versão 1.9.0 (Mac OS X). 2010. Disponível em: <http://gretl.sourceforge.net/gretl_portugues.html> Acesso em: 6 maio 2010.

Or in English, something like that:

COTTREL, Allin; LUCCHETTI, Riccardo. Gretl: GNU Regression, Econometric and Time-series Library, version 1.9.0 (Mac OS X). 2010. Available at: <http://gretl.sourceforge.net/> Accessed: May 6, 2010.

I think this is a good option ;-)

Best regards,
