 *   wine's 'My Documents' to point there. Furthermore, we imply that the user

 *   'My Music' and 'My Video' subfolders under '$HOME/My Documents', if those
 *   do not already exits. We put appropriate symbolic links in place for those,

 * - If there is no 'My Documents' directory in $HOME, we let 'My Documents'
 *   point directly to $HOME. We assume the user to be a unix hacker who does not
 *   want wine to create anything anywhere besides the .wine directory. So, if
 *   there already is a 'My Music' directory in $HOME, we symlink the 'My Music'
 *   shell folder to it. But if not, then we check XDG_MUSIC_DIR - "well known"
 *   directory, and try to link to that. If that fails, then we symlink to
 *   $HOME directly. The same holds fo 'My Pictures' and 'My Video'.
 * - The Desktop shell folder is symlinked to XDG_DESKTOP_DIR. If that does not
 *   exist, then we try '$HOME/Desktop'. If that does not exist, then we leave
 *   it alone.
