ZIPZAP  is  a  small  utility  for  modify,  cut  and  paste  zipfiles
(compressed archives in zip file format, defined by Phil Katz,  PKWARE
Inc.) ZIPZAP lists  contents of zipfiles,  copies or moves  files from
source  zipfiles  to  destination,  remove  files  from  zipfiles  and
encrypt/decrypt files in  zipfiles (registered copies  only).  You  do
not have to  unzip files and  zip again if  you want to  split a large
zipfile into small pieces.  Just use ZIPZAP.  ZIPZAP is fast,  because
it handles files without expansion (and decryption).

----------------------------------------------------------------------

Usage:  ZIPZAP mode src ... [dst]

Items in '[ ]' are optional. '...' means optional repeating.
dst:      zipfile
src:      zipfile [-file ...]

Wildcards in filenames are allowed, if omitted -*.* assumed. Optional
pathname separated with '/' characters may preceede filenames.

List filenames in srczip:            ZIPZAP -l[options] src ...
options: l - long format (includes m,u,t)
	 m - compression method by number
	     0 storing
	     1 shrinking
	     2 reducing 1
	     3 reducing 2
	     4 reducing 3
	     5 reducing 4
	     6 imploding
	       a star (*) after the number means encrypted file
	 u - uncompressed size (excludes s)
	 s - compressed size (excludes u)
	 t - date and time (in hungarian format)
	 k - file comment
Path and file names are always printed.

Copy files from srczips to destzip:  ZIPZAP -c src ... dst
Move files from srczips to destzip:  ZIPZAP -m src ... dst
Remove files from srczips:           ZIPZAP -r src ...
Encrypt files in srczips:            ZIPZAP -e passwd src ...
Decrypt files in srczips:            ZIPZAP -d passwd src ...
Encryption and  decryption is  full compatible  with PKZIP/PKUNZIP  of
PKWARE Inc.

Zipfile in src  and dst may  be ordinary .ZIP  file or self-extracting
.EXE program, except case of very new dst, when ZIPZAP creates  always
.ZIP  type  file  without  self-extract  code.   There  is  no default
filename extension, giving .ZIP or .EXE always required.
Don't give same zipfile as source and destination.

Examples:
 - ZIPZAP -c alpha.zip -*.c bravo.exe -*.h charlie.zip zulu.zip
   copies .c files from alpha.zip, .h files from bravo.exe and all
   files of charlie.zip to zulu.zip.
 - ZIPZAP -r delta.zip -*.c echo.zip -*.c
   removes .c files from delta.zip and echo.zip.
 - ZIPZAP -e"foxTrot georGE" yankee.exe -*.doc -*.txt
   encrypts .doc and .txt files in yankee.exe with 'foxTrot georGE'
   password.
 - ZIPZAP -lmk whiskey.zip -victor/*.?
   lists name, compression method and comment of all files from
   victor subdirectory of whiskey.zip with one character extension.

MS-DOS version  of ZIPZAP  does not  distinguish upper  and lower case
letters in file names.

When listing zipfile content (-l)  file names, sizes etc. are  written
to  standard  output.   All  other  informations  (zipfile name, error
messages) go to standard error.

When modifying a  zipfile (move/remove/encrypt/decrypt source  and all
destination) ZIPZAP creates a temporary file in the current directory,
and after successful closing of them, replaces original with it.

NOTE:  Version  2.0  of  ZIPZAP  does  not  handle  well zipfiles with
authenticity verification.  DON'T use ZIPZAP with them.

----------------------------------------------------------------------

Release history:
2.01 - a minor bug fixed in wildcard interpretation. Increased buffers
       for faster operation.
2.0  - added encryption/decryption features and self-extract code
       handling.
1.10 - beta test release.

What to do:
- proper handling of authenticity verification,
- modifying file attributes within zipfile,
- renaming files within zipfile,
- accepting arguments from list files,
- encryption and decryption in same pass.
