Rebuild a .newsrc file

[Dan_Jacobson at ATT.COM]

Mine takes regular expressions of your liked/disliked groups and sorts
the .newsrc.  Since it depends on sed/awk, etc, I noticed it poops out
on long lines, so I stopped using it.  Plus now that I'm using GNUS, I
hope to find a more high tech solution.

[Cheapest shar, and signature at end...]

echo x - newsrc-rx
sed 's/^X//' >newsrc-rx <<'*-*-END-of-newsrc-rx-*-*'
X# regular expressions for my home-made newsrc sorter.  Dan_Jacobson at ATT.COM
X# this file holds the "loved" newsgroups regular expressions
X# `#' is a comment character at beginning of line.
X# [Was] Always being refined, sloppy, order not too signifigant, especially
X# further down.

X#if .newsrc lines are too long, screws up.
X
X# Loacl issues, and emergency stuff, etc.
