# Shellscript:    xtitle - set title on xterm window
# Author     :    Heiner Steven < Aceasta adresa e-mail este protejata impotriva spamului, JavaScript trebuie activat pentru a putea vizualiza pagina. >
# Requires   :    xprop
# Category   :    Desktop
# Date       :    1995-03-17
# SCCS-Id.   :    @(#) xtitle    1.8 04/02/18
##########################################################################
# Notes
#    o    Thanks to Des Herriott ( Aceasta adresa e-mail este protejata impotriva spamului, JavaScript trebuie activat pentru a putea vizualiza pagina. ) for
#    the way to get a title using "xprop"
#
# Example
#    o    Get the old window title, set the new title to "New Title"
#        OldTitle=`xtitle -g w -w "New Title"`
#
# Changes
# 1995-06-01 hs    Separate settings for title and icon (0.2)
# 1996-03-04 hs    Determine how to echo without newline (0.3)
# 1996-10-01 hs    Get a window title, syntax changed (0.4)
# 1999-10-27 hs    Use "getopts" to preserve whitespace in arguments (1.4)
# 2002-04-09 hs    Added "Requires" header field (1.6)
