LDIRB shows member files in a library along with their create and 
modify dates, sizes, compression method, and their uncompressed 
filenames, and summarizes the number of active, deleted, and free 
library directory entries.  Runs under CP/M 2.2 and CP/M Plus, 
with several enhancements under ZCPR3.  Version 2.1 made several 
display changes, version 2.2 repairs two minor display flaws.
