libgpp4-0 1.3.1-0ubuntu2 (amd64 binary) in ubuntu quantal

 The goal of the ggp4 project is to provide a standalone replacement for
 the CCP4 library for macromolecular crystallography. The library performs
 a number of common tasks in standardized manner. These tasks include file
 opening, parsing keyworded input, and reading and writing of standard data
 formats for electron density maps and X-Ray diffraction data. Programs may
 call this library to ensure compatibility with the CCP4 program suite, as
 well as a similar look-and-feel.
 .
 This package provides a shared library needed to run programs that
 have been linked to libgpp4.so.
