CERNLIB data analysis suite - ZEBRA documentation editor

 CERNLIB is a suite of data analysis tools and libraries created for
 use in physics experiments, but also with applications to other
 fields such as the biological sciences.
 .
 DZedit is an interactive interface to the DZDOC (ZEBRA documentation) system
 developed at CERN. ZEBRA, part of the Packlib library, allows the creation
 of complex data structures in the FORTRAN 77 language; the DZDOC system
 helps to generate and maintain documentation for ZEBRA data structures.
