zutty binary package in Ubuntu Noble s390x

 Zutty is a terminal emulator for the X Window System, functionally
 similar to several other X terminal emulators such as xterm, rxvt and
 others. It is also similar to other, much more modern, GPU-accelerated
 terminal emulators.
 .
 Zutty uses a radically simple, yet extremely efficient rendering
 implementation, coupled with a sufficiently complete feature set to
 make it useful for a wide range of users. It also offers high
 throughput with low latency, and strives to conform to relevant
 standards, either published or de-facto.
 .
 Notice this program requires your GPU OpenGL to support compute,
 fragment and vertex shaders, otherwise it will fail to start.
