Option -d is confusing

The option -d states:
> -d dotfiles - Location of dotfiles, defaults to '~/.dotfiles'
But however inside the script the dotfiles path is built from $HOME/$DOTFILES, so to customize the dotfiles folder path one has to give the path relative to $HOME,
e.g. `dotsync -L -f ~/.cronsync/dotsyncrc -d .cronsync`
Consider changing the help message to avoid issues when using this option. :)
