msc-generator binary package in Ubuntu Noble s390x

 Msc-generator is a program that parses textual Message Sequence
 Chart descriptions and produces graphical output in a variety of file formats.
 .
 Msc-generator heavily borrows in concept from the 0.08 version of
 Michael C McTernan's mscgen. However, it has been completely rewritten from
 scratch and has a much more extensive (and only partially backwards compatible)
 language. The command-line interface is fully backwards compatible with
 mscgen, which enables using Msc-generator's commandline tool everywhere
 where you can use mscgen, but with the richer syntax.
 This includes the many tools integrated with mscgen, such as Doxygen, Sphinx
 and Msctexen.
