About
-----

The tool is intended for developers of software libraries and maintainers of Linux distributions who are interested in ensuring backward binary compatibility.

The tool is developed by Andrey Ponomarenko.

Install
-------

    sudo make install prefix=/usr

###### Requires

* libelf
* libdl
* libstdc++

Usage
-----

    vtable-dumper SHLIB

###### Example

    vtable-dumper /usr/lib64/libstdc++.so.6

###### Note

  Make sure that all dependencies of a target library can be found by `ldd`. Otherwise
  `dlopen()` may fail. Add paths to these libraries to `LD_LIBRARY_PATH` in this case.

###### Options
