Please, make sure your SVN client uses something that matches the
following config. Specially the autoprops part, that way new files
will be added with the right settings. Default config for command line
svn is in ~/.subversion/config. If you use SVN for multiple projects
simultaneously, remember you can use different configs, at least in
cmd line (via --config-dir and for example ~/.subversion/supertuxkart/
with a new config file inside).
