#	Mnemonic:	publish
#	Abstract:	Simple script which copies files that the build script left
#				for export (packages, but could be anything). This expects
#				that all files in /tmp/exportd are to be copied to the 
#				export directory /export The export directory is assumed to be
#				mounted from the outside world as /export, though we will use $1
#				as an override so this can be changed if needed.
