Overview of the installation procedures

The CERNLIB installation procedures perform the following steps:

• Extract the appropriate source code from the master file, e.g. generate the VMS or Unix specific version.
• Split the extracted code into separate files (typically on Unix machines).
• Compile the code
• Generate the libraries

In some cases, additional steps are required, e.g. processing of the KUIP Command Definition File by the KUIP compiler, or the assembly of individual components into a larger library (e.g. PACKLIB is composed of HBOOK [2], KUIP [3], ZEBRA [4] etc.). Currently, source code is typically extracted using the program YPATCHY. If splitting is required, this is performed by FCASPLIT. The basic functionality of these two programs is described below.
