The change done with regard with the CERN library are as follow:

1) Package organization

The main package is cernlib-devel which includes the cernlib static 
libraries, include files and data files. Different versions (corresponding 
with years) of the cernlib can be installed along.

The other packages can't have different versions installed in parallel.

The package cernlib-utils contains the cernlib script which can be used
to compile the cernlib library, and /etc/profile.d/cernlib-<version>.sh
which sets the environment variables usefull for the cernlib.

The package kuipc contains the kuipc interpreter, paw contains the paw
binary, and cernlib-packlib contains the other binaries from the 
cernlib.

2) Filesystem Hierarchy Standard conformance

The upstream Cernlib installs in the subdirectories (bin, lib, include...) 
of the $CERN_ROOT directory which is usually $CERN/$CERN_LEVEL. A mix of
this approach and a standard FHS conformant approach has been followed here.

For the libraries, the Cernlib upstream scheme has been retained, with 
CERN=/usr/lib/cernlib
CERN_LEVEL=2005
and therefore the libraries are in /usr/lib/cernlib/2005/lib. The 
environment variables are set in /etc/profile.d/cernlib-<version>.sh.

For the include files and the data files the subdirectory cernlib/2005
appears in the FHS location, without subdirectories, therefore we have the
equivalences:
$CERN_ROOT/include     ->     /usr/include/cernlib/$CERN_LEVEL/
$CERN_ROOT/share       ->     /usr/share/cernlib/$CERN_LEVEL/

The binary files go into /usr/bin.

3) Removal of non-free code

Debian patches and files from the debian Cernlib package where used to remove
files licensed under non-GPL compatible licences. The script 
cernlib-remove-deadpool and the file cernlib-deadpool.txt which lists 
problematic files can be used in the SOURCES directory with the 
upstream sources to remove the problematic files.

4) Use of external lapack

The cernlib script has been modified to use an external lapack and not
the one provided with the cernlib.

5) kernlib out of packlib

kernlib has been moved outside of packlib. If you use the cernlib script
for linking it should be taken into account, however if you link directly
with packlib you could need to add the kernlib on your link command line.

6) split of motif dependent libs from packlib and pawlib

The motif dependent libs are in libpacklib-lesstif and libpawlib-lesstif.
