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.
