for the lazy guys that are like me :-)
get tortoiseSVN and set it up to update from repository
create a .bat file with 2 lines:
del e:\test\trunk\*.exe
tortoiseproc /command:update /path:"e:\test" /closeonend:3
; first one deletes any and all random .exe-s, second updates to the latest poehud
set the .bat to be run at windows start or put it near PoE
create a shortcut to poehud :-)
