Z-System Library/Archive Utilities (09/30/91).................(3 disks) $15.00
                                                    (Foreign Surcharge:  $3.00)


   This package contains Z-System programs and utilities useful in library and
archive operations.   To round out the package, a number of standby CP/M prog-
rams are also included  (marked with  an  asterisk  after  the  filename).  In
preparing the package, I've tried to select the most  up-to-date and useful of
library/archive tools.  Programs were  NOT  included if  their  functions were
felt to be duplicated or  improved  upon in more  recent and modernized tools.
Such decisions were as follows:

   Not included:                  Included:

   ZLDIR                    ->    LDIRB22
   EXL12                    ->    LBREXT34
   TLZH20*, TYPELZ22        ->    ZLT15
   LRUNZ302                 ->    LX22
   LCRC*                    ->    LREPAIR
   UNARC16*                 ->    UNARCZ13

   Certain tools with the same  function,  however,  WERE  included if one was
felt to have some unique, valuable feature.   For example, while LDIR-B is the
preferred LBR-directory lister,  LLF has the added  ability to  report member-
file CRCs and  member-file indices.   While UNZIP15 is the preferred unZIPper,
UNZIP099 has the  unique  ability to extract from  SFX  (self-extracting)  ZIP
files.   While ZLT15 is the preferred library "typer", LT30 has the ability to
extract a file to a specified DU.

   VLU108 is included even though many complain of its limitations and, in
particular, problems in preserving datestamps.  The development of VLU was 
never fully completed and, depending on your system, it may or may not work 
reliably as a LBR shell.  Still, there are those who like its ZFILER-like
interface and other features (e.g., its handy way of making Crunch comments).
For building LBRs, LPUT is a more reliable tool, is lightning fast, versatile 
and command-line oriented.  LPUT and LBREXT, used either from the command line 
or in a combination of ZFILER macros and ARUNZ scripts, are probably the 
safest Z-System tools to use in building and dissolving LBR files.

   The following  groupings  are  more  or less  as  you will find them on the
distribution disks (some files may have been moved around to fill your partic-
ular disk format).   Each list below contains  the filename,  its size in Khz,
and  a brief description.   Group #1 consists basically of LBR-member handling
utilities:  directory listers, file finders, typers,  extractors,  etc.  Group
#2 provides utilities for handling ARC, ARK, ZIP and ZOO  files, and  Group #3
contains major library shell programs  (including VLU and NULU) and miscellan-
eous programs.
