This distribution is a special version of the CCP4 library, released
under the Lesser GNU Public License version 2.1.

The last version of the CCP4 library covered by a free license was
version 5.0.2. That version was patched by Ralf Grosse-Kunstleve to
address some of the more serious deficiencies of the older library.
It is the patched version of the CCP4 library that forms the basis for
this distribution, which includes a GNU autotools build environment
developed by Paul Emsley and Morten Kjeldgaard.

The reason for creating this public fork of the CCP4 libraries is that
several third party software distributions depend on the CCP4
libraries. However, you cannot create a derived work containing both
CCP4 6.* licensed code and GPL'd code, and distribute the resulting
software, since the GPL demands that the derived work be distributed
without additional restrictions and the CCP4 6.* license imposes
additional restrictions on redistribution - in particular (but not
limited to) an indemnity clause.

The goal of this project -- named gpp4 to distinguish it from CCP4 --
is to provide a drop-in replacement for the non-free CCP4 libraries,
that as carefully as possible will implement the current CCP4 library
interface.
