limits (blocklimits option) and the MAM (readattributes option)
27aug2003 - Added Poweruptime to logpage c

26aug2003 - Initial public release
Patches for tapeutil.c, part of the AIX Atape LPP.
It decodes the data generated by certain logpages.
The output of the inventory command has be changed for easy processing with scripts.
