 'termo' is a library providing an alternative to ncurses' handling of terminal

+input.  ncurses does a terrible job at that, mainly wrt. mouse support which was
+even completely broken for a few years, making it impossible to drag things
+around in applications.  While that one bit has been fixed, it continues to lack
+support for rxvt-unicode's 1015 mode and it's generally incapable of relaying
+certain key combinations.
 
 Since terminal I/O is really complicated and full of special cases, this project
 doesn't aspire to also replace the output part of ncurses, but is rather
 complementary to it.  In the end it makes use of its terminfo library.
