# xearth4 was written years before xearth1, the numbers refer to images,
#       not some version number

# Purpose:
#	Returns return a single up to date xearth graphic image 
#	It may be called from eg http://www.berklix.com/~jhs/
#	which is fed by 2 servers, from one of various virtual domain sub dirs,
#	but must only return an up to date image, not obsolete old images.
#	-
#	For now I force it to a single server for the graphics image.
#	JJLATER it would be nice to have a sub shell, 
#	(& an asserted variable to avoid recursion)
#	so that even if prme server fails, the other server will take over.
#	-
#	To help phone callers decide if the other person may be asleep.
#	As well as the acceptable clueless, I have had agressive bastards
#	phoning from Quebec and California to Germany who refused to keep
#	it short and non demanding, even when told it is 2 to 3 AM in middle
#	of night in Europe.
# Always run 'make check; after editing !
