[xwiki-users] Xwiki database scripts. Xwiki offline documentation

Hi, I am having trouble finding database scripts to generate the XWiki database. Where are these located? Iam also having trouble finding offline documentation (to download) so i can work on XWiki when i am not connected to the internet. Does anyone know the link to download offline documentation (User and Admin guides)? Your help would be much appreciated! Cheers Ian Berry
