=head1 NAME
zipdetails - display the internal structure of zip files
=head1 SYNOPSIS
zipdetails [-v] zipfile.zip
zipdetails -h
=head1 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 (L<SEE ALSO> for details).
=head2 OPTIONS
=over 5
=item -v
Enable Verbose mode
=item -h
Display help
=back
By default zipdetails will output the details of the zip file in three
columns.
=over 5
=item Column 1
This contains the offset from the start of the file in hex.
=item Column 2
This contains a textual description of the field.
=item 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.
=back
If the C<-v> option is present, column 1 is expanded to include
=over 5
=item *
The offset from the start of the file in hex.
=item *
The length of the filed in hex.
=item *
A hex dump of the bytes in field in the order they are stored in the zip
file.
=back
=head1 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.
=head1 SEE ALSO
The primary reference for Zip files is the "appnote" document available at
L<http://www.pkware.com/documents/casestudies/APPNOTE.TXT>.
An alternative reference is the Info-Zip appnote. This is available from
L<ftp://ftp.info-zip.org/pub/infozip/doc/>
The C<zipinfo> program that comes with the info-zip distribution
(L<http://www.info-zip.org/>) can also display details of the structure of
a zip file.

Photography Studio Name Je m'adore fine art portraits
Short Bio I am a portrait photographer, a mother, a wife, a chocoholic and most importantly a woman. I started my portrait studio with the desire to empower women and celebrate all the many things we can be. There is no age limit, no size limit and no weight limit in my studio. Furthermore, there is ZERO judgement.
Full Bio I am a portrait photographer, a mother, a wife, a chocoholic and most importantly a woman. I started my portrait studio with the desire to empower women and celebrate all the many things we can be. There is no age limit, no size limit and no weight limit in my studio. Furthermore, there is ZERO judgement.
As a woman, our thoughts are often triggered by our emotions. Let’s play with that for a moment. Close your eyes and imagine for a moment that you have no limitations… what would that feel like? How would you dream of being photographed? Allow me to make that thought come true for you and capture beautiful images that you will cherish forever.
You deserve it. Come celebrate all your inner moments!
Short Bio Mom, pinup, designer
Full Bio Born and raised in California. Many summer evenings of my childhood could be found in the garage handing my dad a wrench or holding a flashlight. The smells of exhaust and motor oil bring back those happy memories, because of that, I can often be found at car shows. Most of my time is occupied with wrangling my two rambunctious young sons but when I have some free time I like to create. Whether that’s from either side of a lens, leaning over a craft table or dabbling away on a design, my mind is always thinking up a new creation.
