Sawfish.desktop isn't installed

Hi,

John I don't understand this code in Makefile.in :

        if [ -d $(DESTDIR)$(GNOMEDIR)/share/gnome/wm-properties ]; then \
          rm -f 
$(DESTDIR)$(GNOMEDIR)/share/gnome/wm-properties/Sawmill.desktop; \
          $(INSTALL_DATA) $(srcdir)/Sawfish.desktop 
$(DESTDIR)$(GNOMEDIR)/share/gnome/wm-properties; \
        fi

Why the test for the /share/gnome/wm-properties directory ?
