Raw strings in path are not the best idea: if the path happens to end with "\", 
you may not notice it in your editor, but you'll get a syntax error because the 
backslash escapes the end quote. Especially a problem if you don't code the path 
yourself, but it's provided programmatically or by the user. I know because I 
made this error :). It would be better to just use forward slashes - works under 
Windows too.
