|Description||X terminal-emulator similar to xterm, but smaller compatible with xterm while using much less swap space. It is mainly intended for use at sites which use large numbers of X terminals but may also be useful on single workstations that are short of memory. The main way that xvt achieves its small size is by avoiding the use of the X toolkit.|
