It's a bit more complex than that :)

info -c: show cvswrappers as seen by the client
info -s: show cvswrappers as seen by the server

These will often be the same... it's just the mechanism used to get the 
lists is different (info -s isn't terribly useful but can be used to 
show discrepancies if there's a problen).

Early on in the client/server negotiation the client extracts the list 
of cvswrappers from the server, which is added to its list.

The client then sends the list, minus the entries that were sent from 
the server earlier, back to the list, which adds that to its list.

So the client sees client+server, and the server sees server+client (the 
distinction isn't so important as most processing is done server-side).

On top of that, there's also temporary entries from the local 
.cvswrappers files.  These are added per-directory by the client before 
it's sent to the server.  cvs info doesn't show these.

 From your original dump it looks like you're actually getting both (eg. 
*.zip is there twice) but they're the same - your cvswrappers isn't what 
you think it is.
