Guix

Rxvt-unicode (urxvt) is a colour vt102 terminal emulator intended as an xterm replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability. It supports unicode, XFT and may be extended with Perl plugins. It also comes with a client/daemon pair that lets you open any number of terminal windows from within a single process.
