=begin usage
Incremental (or one-shot) importer of a slrnpull news spool.

Since the news spool can appear as an MH folder, you may also use
lei from public-inbox 2.0+ to convert it:

	lei convert mh:$SLRNPULL_ROOT/news/foo/bar -o v2:/path/to/inbox/
	# (and `lei daemon-kill' if you don't want the daemon to linger)

But if you want to use this script:

	export ORIGINAL_RECIPIENT=address@example.com
	public-inbox-init -V2 $INBOX $INBOX_DIR $HTTP_URL $ORIGINAL_RECIPIENT
	./import_slrnspool $SLRNPULL_ROOT/news/foo/bar
