Good ${current_time_of_day} again!
I've made some changes:
0 - cffi-greovel file with termios constants (icanon etc.) is generating automatically from constants list;
1 - non posix features, such iutf8 are `#+linux' or `#+bsd' marked.
I've run it only under linux, and all `#+bsd' marked features still need to be checking under BDS box (currently i don't have any).
Still hooping, that it can be usefully, Nikolay V. Razbegaiev.
