{G}	Well, I got all the parts of the NetHack 3.0j post, and un-zoo'd it
{G} on my PC.  However, both of the .zoo files are 37 bytes bigger than the
{G} sizes given in the header of the first part, and "sum" reports different
{G} figures as well.

That's odd.

{G} The individual file sizes are correct, though.  I do not
{G} have brik do I did not test it that way.  Any comments/suggestions?  Could
{G} there be a virus?

There could, but I doubt it.  The c.b.i.p moderator is *awful* careful
about such things.

{C} I too noted the difference.  Brik checksums were off as well.

Well when the file size differs, I'd expect so.

{C} I then extracted the files and scanned them with F-PROT's F-SCAN and
{C} McAfee's SCAN (no, not 78 :-).  Both programs reported a clean machine.
{C} The game seems to run fine.

As did I, and (I'm sure) as did Mr. Davidsen.

{C} Anyone asked the authors yet?

Ok here's MHO.

Comparing the uudecoded zoo files to the copies I have (of the ones I
submitted) I note that there is now a comment of
	">> Nethack game v3.0.10, disk one files"
added to the first archive and one that says
	">> Nethack game v3.0.10, disk two files"
added to the second.

I can only expect that these were added by Mr. Davidsen (or some other
reviewer), but since these were not in the zoo files I submitted
I could not anticipate them in the checksums that I submitted with
it.  (note there is a typo in the full listing zoo CRC for GUIDEBK.TXT
is "a723" not "s723" :-)

Note also that only the complete archive zoo CRC and brik checksums are
off.  The others listed (verified by zoo vC <archive.zoo>) are correct.

No.  I don't think we have any troubles here.

Hack On!
