While I see little value in the original poster's desires, Doug's comment
on Skip's solution is easily taken care of with out AI type code.  To wit:

	cut -d: -f1 .newsrc |

	awk -F. '
	{
		for (i = NF; i >= 1; i--)
			printf("%s ", $i)
		print ""
	}' |

	paste -d: - .newsrc |

	sort |

	cut -d: -f2- > puke

And should you not have cut (a Xenix related deficiency) let me know
and I'll provide an awk/shell script to mimic it.  Or perhaps there
is a ???.sources version around.
