The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.
minor feature: - Add optional feature to capture text copied to clipboard at the time of copying rather than at the time the clipboard contents are requested for pasting. - Improve a special case where the -e option was used to pass a single-quoted command via luit, by wrapping it in a sh -c .
