[net.micro.cpm] super LU-like program

LIN@mit-xx.ARPA (10/03/86)

I'm looking for a program that 

-- adds/deletes members to a library
-- allows viewing members of the library (even if squeezed)
-- squeezes and unsqueezes members
-- allows mass operations 

Some time ago, I heard of a program would do most of this; I think
this program was called NSWP, but it had bad bugs in it (that trashed
directories?); I seem to recall that these bugs were being fixed, but I
haven't heard anything since then (several months ago).

Can anyone help?  (P.S. I tried loading the file called NSWP.LBR from
SIMTEL20, but when I tried to use LU on it, I got a msg saying "Old
library: no directory, and then LU aborted on me.)

Thanks.
