libeio-dbg 1.7.7-1ubuntu1 (amd64 binary) in ubuntu utopic

 This library is part of the Enlightenment Foundation Libraries (EFL). It is
 intended to provide non-blocking IO by using thread for all operations that
 may block. It should integrate all the features/functions of Ecore_File that
 could block.
 .
 This package contains unstripped shared libraries. It is provided primarily
 to provide a backtrace with names in a debugger, this makes it somewhat easier
 to interpret core dumps. The libraries are installed in /usr/lib/debug and
 are automatically used by gdb.
