ZIPDETAILS(1)	       Perl Programmers	Reference Guide		 ZIPDETAILS(1)

NAME
       zipdetails - display the	internal structure of zip files

SYNOPSIS
	   zipdetails [-v] zipfile.zip
	       zipdetails -h

DESCRIPTION
       Zipdetails displays information about the internal record structure of
       the zip file. It	is not concerned with displaying any details of	the
       compressed data stored in the zip file.

       The program assumes prior understanding of the internal structure of a
       Zip file. You should have a copy	of the Zip APPNOTE file	at hand	to
       help understand the output from this program ("SEE ALSO"	for details).

   OPTIONS
       -v   Enable Verbose mode

       -h   Display help

       By default zipdetails will output the details of	the zip	file in	three
       columns.

       Column 1
	    This contains the offset from the start of the file	in hex.

       Column 2
	    This contains a textual description	of the field.

       Column 3
	    If the field contains a numeric value it will be displayed in hex.
	    Zip	stored most numbers in little-endian format - the value
	    displayed will have	the little-endian encoding removed.

	    Next, is an	optional description of	what the value means.

       If the "-v" option is present, column 1 is expanded to include

       o    The	offset from the	start of the file in hex.

       o    The	length of the filed in hex.

       o    A hex dump of the bytes in field in	the order they are stored in
	    the	zip file.

TODO
       Error handling is still a work in progress.  If the program encounters
       a problem reading a zip file it is likely to terminate with an
       unhelpful error message.

SUPPORT
       General feedback/questions/bug reports should be	sent to
       <https://github.com/pmqs/IO-Compress/issues> (preferred)	or
       <https://rt.cpan.org/Public/Dist/Display.html?Name=IO-Compress>.

SEE ALSO
       The primary reference for Zip files is the "appnote" document available
       at <http://www.pkware.com/documents/casestudies/APPNOTE.TXT>.

       An alternative reference	is the Info-Zip	appnote. This is available
       from <ftp://ftp.info-zip.org/pub/infozip/doc/>

       The "zipinfo" program that comes	with the info-zip distribution
       (<http://www.info-zip.org/>) can	also display details of	the structure
       of a zip	file.

       See also	Archive::Zip::SimpleZip, IO::Compress::Zip,
       IO::Uncompress::Unzip.
