#I wrote this after seeing someone running 'gone'.
#I don't remember the author's name.
#It looks like 'gone' but lacks lots of features
#'gone' has. Afterall it's a script!!!
#Better than 'lock' anyway :-)
#'gone' is written in C.
#
#I used ANSI control characters to give it a good face, so
#should work in any vt series terminal or true emulation.
#
#Hastily written! 
#
mesg n  #mail or talk won't mess up the screen.
