end of line whitespace

[Robert Hicks]

I know that in some IDE's I can check a box that causes the IDE to 
automatically strip trailing white space. Does Vim have a switch to do 
that or do I need to do:

autocmd BufWritePre * %s/\s*$//e
It would be nice to have a "set stripwhitespace" if that is the case but 
I guess that is the power of Vim.
