xgterm binary package in Ubuntu Noble armhf

 XGterm provides a Tek 4012 compatible graphics terminal emulation for
 IRAF, plus a datastream driven widget server capability using the
 Object Manager to provide full access to the underlying toolkit and
 widget set. The Gterm graphics window operates almost identically to
 the xterm Tek window, however there are extensions for implementing
 full-screen cursors, imaging, area fills, colors, graphics erasure,
 a "status line" and so on.
