UNARC is a CP/M 2.x+ utility which lists, types, prints, checks,  and
extracts files in archive libraries (*.ARC or *.ARK files).  Includes
separate  program versions for Z80 (UNARC.COM) and 8080 (UNARCA.COM).
Assembler overlay file supports installation for RCP/M's and  special
options.  Version 1.6 corrects a bug which caused incorrect CRC error
warning message when extracting some files to disk.  UNARC16.ARK is a
"self-unpacking" archive:  Rename it to UNARC16.COM, and then run it!
