teseq binary package in Ubuntu Lunar s390x

 GNU Teseq is a tool for analyzing files that contain control characters
 and terminal control sequences, by printing these control sequences and
 their meanings in readable English. It is intended to be useful for
 debugging terminal emulators, and programs that make heavy use of
 advanced terminal features such as cursor movement, coloring, and other
 effects.
 .
 Teseq is useful for:
   - Creating animated, interactive demos to run on the terminal (see
     https://asciinema.org/a/7445 for a video on how to do this).
   - Knowing the exact output of a program (did it have spaces at the
     end of the line? Or maybe it contains invisible control characters?).
   - Examining a text file's contents unambiguously, like cat -v or the ed
     program's l command (but with much more information).
   - Stripping control sequences from a text file, e.g. to produce a plain
     ascii text file from a typescript file generated by the script command.
   - Examining the invisible control sequences within a text file, that affect
     graphical formatting or character encoding, in order to understand how
     they work and where they appear in the file.
   - Debugging graphical terminal applications, and terminal emulators.
