+.B minizip
+is a simple tool which allows the extraction of compressed file
+archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
+written as a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR unzip (1)
+program.
+.SH OPTIONS
+A number of options are supported.  With the exception of
+.BI \-d\  tempdir
+these must be supplied before any
+other arguments and are:
+.TP
+.BI \-l\ ,\ \-\-v
+List the files in the archive without extracting them.
+.TP
+.B \-o
+Overwrite files without prompting for confirmation.
+.TP
+.B \-x
+Extract files (default).
+.PP
+The
+.I zipfile
+argument is the name of the archive to process. The next argument can be used
+to specify a single file to extract from the archive.
+
+Lastly, the following option can be specified at the end of the command-line:
+.TP
+.BI \-d\  tempdir
+Extract the archive in the directory
+.I tempdir
+rather than the current directory.

+.SH AUTHOR
+This program was written by Gilles Vollant.  This manual page was
+written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
+was added by Dirk Eddelbuettel <edd@debian.org>.

+.SH NAME
+minizip - create ZIP archives
+.SH SYNOPSIS
+.B minizip
+.RI [ -o ]
+zipfile [ " files" ... ]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the creation of compressed file archives
+in the ZIP format used by the MS-DOS utility PKZIP.  It was written as
+a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR zip (1)
+program.
+.SH OPTIONS
+The first argument supplied is the name of the ZIP archive to create or
+.RI -o
+in which case it is ignored and the second argument treated as the
+name of the ZIP file.  If the ZIP file already exists it will be
+overwritten.
+.PP
+Subsequent arguments specify a list of files to place in the ZIP
+archive.  If none are specified then an empty archive will be created.
+.SH SEE ALSO
+.BR miniunzip (1),
+.BR zlib (3),
+.BR zip (1).
+.SH AUTHOR
+This program was written by Gilles Vollant.  This manual page was
+written by Mark Brown <broonie@sirena.org.uk>.
