libpacklib-lesstif1-gfortran binary package in Ubuntu Focal arm64

 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.
 .
 The packlib library includes a great deal of CERNLIB core functionality.
 Best-known are probably the MINUIT function minimization routines, the
 HBOOK histogramming routines, and KUIP (Kit for a User Interface Package).
 Other subsystems include CSPACK, a set of client-server routines; FFREAD,
 a format-free input processing system for FORTRAN; and ZEBRA, a data
 structure management package.
 .
 This package includes the graphical functionality of KUIP, the CERNLIB
 Kit for a User Interface Package. This library has been split off
 from packlib so that the packlib packages need not depend upon
 the X and Lesstif libraries.
 .
 This package was formerly named libkuipx11-1. The text-based functionality
 of KUIP can be found in the libpacklib1-gfortran package.
 .
 Note that in order to compile and link programs against this library, you
 must also install the libpacklib-lesstif1-dev package.
