streamzip - create a zip file from stdin
producer | streamzip [opts] | consumer
producer | streamzip [opts] -zipfile=output.zip
This program will read data from stdin, compress it into a zip container and,
by default, write a streamed
zip file to stdout. No temporary files are created.
The zip container written to stdout is, by necessity, written in streaming
format. Most programs that read Zip files can cope with a streamed zip file,
but if interoperability is important, and your workflow allows you to write the
zip file directly to disk you can create a non-streamed zip file using the "zipfile" option.
Create a Zip64-compliant zip container.
Use this option if the input is greater than 4Gig.
Default is disabled.
Write zip container to the filename F.
Use the "Stream" option to enable the creation of a streamed zip file.
This option is used to name the ``file'' in the zip container.
Default is '-'.
Ignored when writing to stdout.
If the "zipfile" option is specified, including this option
will trigger the creation of a streamed zip file.
Default: Always enabled when writing to stdout, otherwise disabled.
Compress using method ``M''.
Valid method names are
* store Store without compression
* deflate Use Deflate compression [Deflault]
* bzip2 Use Bzip2 compression
* lzma Use LZMA compression
Note that Lzma compress needs IO::Compress::Lzma to be installed.
Default is deflate.

When to use a Streamed Zip File
A Zip file created with streaming mode enabled allows you to create a zip file
in situations where you cannot seek backwards/forwards in the file.
A good examples is when you are
serving dynamic content from a Web Server straight into a socket
without needing to create a temporary zip file in the filesystsm.
Similarly if your workfow uses a Linux pipelined commands.
