Great you're sponsoring cool-retro-term. Just FYI, there's a slightly tweaked packaging branch I put together, in https://github.com/barak/cool-retro-term/ branch "debian". The main differences are it generates the man page using help2man at build time, and provides x-terminal-emulator.
See also https://github.com/Swordfish90/cool-retro-term/issues/332 Never quite crossed the energy barrier to dput it though; mainly used it because I like to use the program when teaching/lecturing especially about FORTRAN and such. Cheers, --Barak.
