NAME
       streamzip - create a zip file from stdin

SYNOPSIS
	   producer | streamzip [opts] | consumer
	   producer | streamzip [opts] -zipfile=output.zip

DESCRIPTION
       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.

   OPTIONS
       -zip64
	    Create a Zip64-compliant zip container. Use this option if the input is greater than 4Gig.

	    Default is disabled.

       -zipfile=F
	    Write zip container to the filename "F".

	    Use the "Stream" option to force the creation of a streamed zip file.

       -member-name=M
	    This option is used to name the "file" in the zip container.

	    Default is '-'.

       -stream
	    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.

       -method=M
	    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
		* xz	   Use xz compression
		* zstd	   Use Zstandard compression

	    Note that Lzma compress needs "IO::Compress::Lzma" to be installed.

	    Note that Zstd compress needs "IO::Compress::Zstd" to be installed.

	    Default is "deflate".

       -0, -1, -2, -3, -4, -5, -6, -7, -8, -9
	    Sets the compression level for "deflate". Ignored for all other compression methods.

	    -0 means no compression and -9 for maximum compression.

	    Default is 6

       -version
	    Display version number

       -help
	    Display help

   Examples
       Create a zip file bt reading daa from stdin

	   $ echo Lorem ipsum dolor sit | perl ./bin/streamzip >abcd.zip

       Check the contents of "abcd,zip" with the standard "unzip" utility

	   Archive:  abcd.zip
	     Length	 Date	 Time	 Name
	   ---------  ---------- -----	 ----
		  22  2021-01-08 19:45	 -
	   ---------			 -------
		  22			 1 file

       Notice how the "Name" is set to "-".  That is the default for a few zip utilities whwre the member name is not given.

       If you want to explicitly name the file, use the "-member-name" option as follows

	   $ echo Lorem ipsum dolor sit | perl ./bin/streamzip -member-name latin >abcd.zip

	   $ unzip -l abcd.zip
	   Archive:  abcd.zip
	     Length	 Date	 Time	 Name
	   ---------  ---------- -----	 ----
		  22  2021-01-08 19:47	 latin
	   ---------			 -------
		  22			 1 file

   When to write a Streamed Zip File
       A Streamed Zip File is useful 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.
