		LGFV v2.10 	(c) 1993-2000 by George Lyapko
		----------------------------------------------
		
1.Short description
-------------------
	LGFV is small and fast MS-DOS archives viewer.

2.Why LGFV?
-----------
	þ You need no archivers themselves to view archives
	þ Archive will be correctly recognized regardless of its extension
	þ It recognizes 90 types of archive formats
	þ It's really fast
	þ It needs approx. 39kB free RAM
	þ It has excellent feature: you can adjust archive datestamp to that
	  of latest file within archive (when you download some archive - 
	  the date of file will be the date of download, not the original 
	  date). You may set the name of text file with names of file to
	  ignore while setting datestamp (for example, if you don't want
	  to set the date of archive downloaded from BBS to the date of
	  file FILE_ID.DIZ within this archive, you may use this feature).
	þ The output may be redirected to file under DOS (with > or >>).

3.Usage
-------
	LGFV [/albmd@<filename>] mask1 [mask2..],

	where

	a		modifies archive datestamp to the datestamp of 
			the latest file (exclude those in ignore list) within
			archive
	l		long listing(with path)
	b		brief listing(only file names)
	m		datestamp in MM-DD-YYYY format (default DD-MM-YYYY)
	d		ignore directories
	@<filename>	specify file with filenames to ignore(for use with /a)

	Ignore list has some limitations:
	a) no wildcards;
	b) no spaces or empty lines;
	c) File size <= 1024 bytes;
	d) DOS filenames 
	   (case is ignored,filename-max 8 char,'.',extension-max 3 char);

5.Formats, which are not listed by LGFV
---------------------------------------
Here is a brief list of archives, which are not (and probably never will
be) supported by LGFV (file headers are compressed or encrypted):
-ACB by George Buyanovsky;		-AIN by Transas Marine Ltd.;
-AR7 by Timothy R.Ericsson;		-ARS Sfx by Stepanyuk Oleg;
-BTSPK dy Hidasi Jozsef;		-DeepFreezer by BinaryTechnologies;
-ESP by GyikSoft & Microlab;		-HPA by Hungarian Pirate's Alliance;
-IMP by Technelysium Ltd.;		-JAR by Robert Jung;
-LZA by African Chief;			-PAR by Philipp Druyts;
-RKIVE by Malcolm Taylor;		-UC2 by AIP-NL;
-UHARC by Uwe Herklotz;			-TGZ,TAZ,Z,GZ...

LGFV also currently doesn't support (maybe in future:-):
-Sfx-archives with EXE-stub larger than 64kB, 
-CPAC v1.35 by Digital Strategies Inc.,
-I5COMP v1.0 by fOSSiL,
-JARCS v0.94 by Junichi Uekawa.

6.Description of output
-----------------------
First position of filename in normal listing will be '+' if file has path.

	Original size:
LBR,LU,TAR	- size of stored file data (if compressed - size of compressed
		  data)
JRC,TSC,ZAR	- stores no original size

	Compressed size:
LU,TAR 		- size of file within archive (aligned to block boundary)
BLI,EXP,NSK,
SBX,SQW,XTR	- size of compr.block (with header)
77S,AKT,ASD,CAB,PAQ,UFS,
X1(only solid blocks),
YAC		- stores no compr.size for each file in archive. That's why
		  in LGFV listing only total compressed size is significant.

	CRC:
AKT,ARG,ARH,BLI,CAB,DSL,EXP,FLH,GTH,HPK,HAP,IBM,ICE,JRC,LS,LU,
NSK,NUF,PAQ,QF1,QFC,
RNC,SBX,SYN,TAR,TSC,
XPA,XTR,Z,ZAR	- stores no file CRC (as I know)
LZO		- CRC is shown for last block in chain(in most cases this is
		  CRC for whole file) but LZOP may not store CRC at all
ARX 		- only lower byte significant
RED		- I don't know if CRC shown by LGFV is valid
all others	- if CRC16 was used then lower word significant
		  else CRC32

	Date/Time:
LBR,LU		- I really don't know whether the date/time shown by LGFV
		  is valid
GTH,MAR,RNC,SAR,
SYN,XIE,XTR,ZAR	- stores no datetime stamp (so usage of '-a' switch
		  is useless)

	Flags:
DWC		- only password and comment are valid (no attr)
ARG,ARH,FLH,IBM,LBR,
LS,LU,SYN,RAX,RNC,
TSC,RED(?)	- stores no attributes and method
AK7,ARC,ICE,DSL,
JRC,NUF,XTR,WA	- stores no attributes (as i know)
R-Readonly [TAR: (attr & 0222o) == 0]
H-Hidden   [TAR: (attr & 0444o) == 0]
S-System   [TAR: (attr & 7000o) <> 0]
D-Directory label
A-Archive
P-Password applied to this file
X-File has continuation or beginning in another volume
C-File has attached comment
M-Method used
AK7:
	0	stored
	1	data
	2	text
AMG:
	8	super fast compression (AMGC,SPA,OOP- "-ms",SKY - "-m0")
	0	other kind of compression
ARC:
	0	stored
	1	RLE
	2	squeezed
	3-7	different LZW
	8	crushed (PAK), trimmed (ARC by SEA)
	9	distilled (PAK)	
ARQ:
	0	stored
	1	crushed
BIX:
	0	stored

	š	method 99
JRC:
	0	stored
	2	compressed
LHA:
	0	-lh0- or -lz4-
	1-9	-lh?-
	Z	-lz5-
	S	-lzs-
	U	unknown method
LZO:
	1	LZO1X-1
	2	LZO1X-1(15)
	3	LZO1X-999
SQW:
	1	stored
	0	imploded
X1:
	s	part of solid block
ZAR:
	0	maximale geschwindigkeit
	1	schnell
	3	normal
.......................to be continued
7.Some problems
---------------
-ARC v7.12 multiple volumes are not detected.
-ZIP multiple volumes are not detected.
-PAK archives are shown without path information (I must desperately
 change algo's).
-LGFV doesn't support multiple volumes (there are some technical reasons).
 If you want view multiple volumes of ARJ, for example, try
 LGFV arc.A?? and you'll receive listing of all volumes separately:
 arc.arj,arc.a01,arc.a02, etc.
-ARX sometimes creates damaged archives (if file could not be compressed)
 and SFX-files (always?). They could not be listed properly or even detected
 by LGFV.
-BLINK version 2.50 has algorithmic bug(seems to be fixed in 2.51):
 if you compress files with lower byte of datestamp is equal to 1 or 0
 (eg. August 1,XXXX or August 0,XXXX), such archive could not be listed
 properly (with BLINK itself or with LGFV)...

8.What's new(since v2.02)
-------------------------
	v2.10	- ZIP archives attributes fixed
		- attributes are shown as letters, not as '+' (VC compatibility)
		- exit code fixed to be 0 if all OK
	v2.09	- fixed some newer RAR archives (mostly OS/2 aware) processing
	v2.08	- fixed Z archives processing (archives got a wrong date)
		- fixed HA archives processing (wrong time)
		- fixed misspelling bug
		- fixed BOA archives with image compression processing
		- added AKT v.70Beta2(AK7) recognition
	v2.07	- added Quantum v0.90 recognition
		- fixed Quantum v0.96 archives processing (wrong filenames)
		- added switch to show datetime in MM-DD-YYYY format
		- time is shown as HH:MM:SS now
		- filenames are shown in archive internal case (not
		  always in uppercase)
		- archive creation date (external) is also shown
		- * now means *.* (not *. as before)
		  (for example,
		  	LGFV ARCH* is equivalent to
		  	LGFV ARCH*.*)
		  (thx. Disen Abella for bug reporting and some ideas)
	v2.06	- added AKT v.5b(format changed) support (+SFX)
		- added ZAR v2.6 support
		- added XTREME v1.06 support
		- added SEMONE v0.4-0.5 support
		- added BLINK v2.55 support
	v2.05	- added AKT v.58 support (+SFX)
		- added FLH (Flash v1.00) support
		- added ARG support
		- added EXP1 support
		- added WA (Waveform Archiver) support
		- added GTH (Gather) support
		- added LBR(LU86),LU(LUPC) support
		- UNIX(CP/M) dates before Jan 1,1980 now are shown
		  as 00-00-80 (not year 2100+)
		- fixed LZOP support (multiple blocks)
	v2.04	- added CHARC v1.2 SFX support
		- added PAQ(oPAQue) support
		- fixed solid UFA/777 datetime detection:
		  previous version show last access datestamp
		- fixed ZET with subdirectories procession
		- BSA archives are detected more precisely
		- some SFX-archives detection fixed
		- added Synetic,Links LS,IBM Pack support
		  (thx. Philip Helger for suggestion)
		- added SBX v1.4 SFX-archives detection
	v2.03	- added BLINK spec 2 step 51 format support
		- added UFA 0.03/0.04 solid archive support
		- added 777 0.03/0.04 solid archive support
		- added UFA 0.00 support (pf-f-f, it was hard to
		  distinguish it from later UFA versions)
		- added UFA/777 password detection
		- added CAR support
9.To do
-------
- more archive formats (listed in part 2 of section 5).
  If you know archive formats, not listed in sections 4 and 5, please
  tell me
- recursion?
- something else?
