        !             3: funzip \- extract from a ZIP archive file as a filter
        !             4: .SH SYNOPSIS
        !             5: [...]  |  \fBfunzip\fP [ password ]  |  [...]
        !             6: .SH ARGUMENTS
        !             7: .IP [\fIpassword\fP] \w'[\fIpassword\fP]'u+2m
        !             8: Optional password to be used if ZIP archive is encrypted.  Decryption
        !             9: may not be supported at some sites.  See DESCRIPTION for more details.
        !            10: .PD
        !            11: .SH DESCRIPTION
        !            12: .I FUnZip
        !            13: acts as a filter; that is, it assumes that a ZIP archive is being piped into
        !            14: standard input, and it extracts the first member from the archive to stdout.
        !            15: Given the limitation on single-member extraction, \fIFUnZip\fP is most
        !            16: useful in conjunction with a secondary archiver program such as tar(1).
        !            17: The following section includes an example illustrating this usage in the
        !            18: case of disk backups to tape.
        !            19: .PD
        !            20: .SH EXAMPLES
        !            21: To use \fIFUnZip\fP to extract the first member file of the archive test.zip
        !            22: and to pipe it into more(1):
        !            23: .PP
        !            24: .IP "\t\fIfunzip\fP < test.zip | more"
        !            25: .PP
        !            26: To use \fIFUnZip\fP to test the first member file of test.zip (any errors
        !            27: will be reported on standard error):
        !            28: .PP
        !            29: .IP "\t\fIfunzip\fP < test.zip > /dev/null"
        !            30: .PP
        !            31: To use \fIZip\fP and \fIFUnZip\fP in place of compress(1) and zcat(1) for
        !            32: tape backups:
        !            33: .PP
        !            34: .IP "\ttar cf \- . | \fIzip\fP \-7 | dd of=/dev/nrst0 obs=8k"
        !            35: .IP "\tdd if=/dev/nrst0 ibs=8k | \fIfunzip\fP | tar xf \-"
        !            36: .PP
        !            37: (where, for example, nrst0 is a SCSI tape drive).
        !            38: .PD
        !            39: .SH LIMITATIONS
        !            40: There is presently no way to extract any member but the first from a ZIP
        !            41: archive.  This would be useful in the case where a ZIP archive is included
        !            42: within another archive.
        !            43: .PP
        !            44: An alternate mechanism for passing the password to \fIFUnZip\fP would
        !            45: be preferable to putting it on the command line.
        !            46: .PP
        !            47: \fIFUnZip\fP would be useful under OS/2, too.
        !            48: .PP
        !            49: The functionality of \fIFUnZip\fP should be included in \fIUnZip\fP
        !            50: directly (future release).
