      VTE is a library (libvte) implementing a terminal emulator widget for
      GTK, and a minimal sample application (vte) using that.  Vte is
      mainly used in gnome-terminal, but can also be used to embed a
      console/terminal in games, editors, IDEs, etc. VTE supports Unicode and
      character set conversion, as well as emulating any terminal known to
      the system's terminfo database.
