$ rpmpeek libxfce4util-4.2.3.2-alt1.1.i586.rpm objdump -Tw ./usr/lib/libxfce4util.so.1.0.9 |fgrep -m1 -C1 .xfce.LICENSES
00009380 l    d  .rodata        00000000              .rodata
0000a220 l    d  .xfce.LICENSES 00000000              .xfce.LICENSES
0001501c l    d  .eh_frame      00000000              .eh_frame
$
