[Gvsig_english] gvSIG silent installation on Windows

[Neal Mann]

/I need to deploy gvSIG in a Windows computer lab, and I'd like to do it 
silently with a simple batch script.  I can't find any documentation 
about the installer, and the "/S" switch doesn't work.

Has anyone done an automated and/or silent installation of gvSIG on 
Windows?  I looked at the build.xml file in the git repo, but I'm not 
familiar with IzPack.
