-      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.
