title: TortoiseSVN on USB key
body: <p>I am trying to use tortoiseSVN to manage some files that I need to transfer between my computers at work and at home.  Do I need to install TortoiseSVN on the USB key that I use to transfer the files?  Or will TortoiseSVN work without me having to do so?  If I need to install to the key, is that possible?  The .msi installer I downloaded doesnt' allow me to specify the directory for installation.</p>
