# ** saveaday.scr **  Just make a yyddd subdir and copy dated gif files there.

#          (on cimss, in home2/www/goes/realtime/face/arc)

#  Update:
#  25jun2002 -gsw- vers for Florida-area CRYSTAL experiment.
#  07jun2002 -gsw- incl gsaih*.gif files to the copy.
#  07jun2002 -gsw- add upihg11arc.scr (build list files for G11 gifs).
#  06may2002 -gsw- add upihdpiarc.scr (build gif list text files to animate).
#  28jan2002 -gsw- for IHOP, run for YDA at 02z tda.
#  27sep2001 -gsw- actually no need at the moment for using yda.
#  26sep2001 -gsw- make automatic (either yda(default) or entered day).
