+ * wine's 'My Documents' to point there. Furthermore, we imply that the user
+ * is a Windows lover and has no problem with wine creating 'My Pictures',
+ * '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,
+ * too.
+ * - 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, we symlink it to $HOME directly. The same
+ * holds fo 'My Pictures' and 'My Video'.
+ * - The Desktop shell folder is symlinked to '$HOME/Desktop', if that does
+ * exists and left alone if not.
+ * ('My Music',... above in fact means LoadString(IDS_MYMUSIC))
