2113  *   too.
2114  * - If there is no 'My Documents' directory in $HOME, we let 'My Documents'
2115  *   point directly to $HOME. We assume the user to be a unix hacker who does not
2116  *   want wine to create anything anywhere besides the .wine directory. So, if
2117  *   there already is a 'My Music' directory in $HOME, we symlink the 'My Music'
2118  *   shell folder to it. But if not, then we check XDG_MUSIC_DIR - "well known"
2119  *   directory, and try to link to that. If that fails, then we symlink to
2120  *   $HOME directly. The same holds fo 'My Pictures' and 'My Video'.
2121  * - The Desktop shell folder is symlinked to XDG_DESKTOP_DIR. If that does not
2122  *   exist, then we try '$HOME/Desktop'. If that does not exist, then we leave
2123  *   it alone.
