Rxvt and Cannot find terminfo entry for ‘rxvt-unicode’

Great lightweight editor that supports Unicode, but seems to be neglected by Linux distros, since starting e.g. screen (what would really our life be like without it…) raises only:

Cannot find terminfo entry for ‘rxvt-unicode’

Remedy:

$ cat "URxvt*termName: rxvt" ~/.Xdefaults
