[xwiki-devs] Getting Source Repository - Newbie question

Hi, I am trying to get xwiki platform sources from TortoiseSVN. I have followed this instructions: http://dev.xwiki.org/xwiki/bin/view/Community/SourceRepository but I think I must make changes at Tortoise or something like that, because when I try to checkout http://svn.xwiki.org/svnroot/xwiki/platform/ recursively and HEAD revision I download more than 2GB of contents (I have only arrived to 2GB, then my RAM dies). I suppose I should only download last xwiki 2.0, could you tell me the essentials I need to compile platform? Thanks and sorry for this stupid question!!
