title: How do I determine the version of a library in Unix without 'strings' or 'what'
body: <p>I have a copy of the expat XML processing library on an embedded system running busybox 0.61.  I need to find out the version of the library, but I don't have the 'strings' or 'what' applications on the image, nor can I recompile the image.  These busybox images that I'm forced to use a grossly impaired.</p>
  
  <p>Is there any way for me to find out what version of the expat library is installed without the 'strings' or 'what' utilities ? The library is shared (libexpat.so.1)</p>
