[vset compress zip]
[include compress/header.inc]
[para]
The command is based on the deflate compression algorithm as specified
in RFC 1951 ([uri http://www.rfc-editor.org/rfc/rfc1951.txt]) and as
implemented by the zlib compression library
([uri http://www.gzip.org/zlib/]).
See also RFC 1950 ([uri http://www.rfc-editor.org/rfc/rfc1950.txt])

[lst_item "[option -nowrap] [arg boolean]"]
If set to [const true] the command will not create the zip specific
header (See RFC 1950) normally written before the compressed data. The
options defaults to [const false].
It has to be used when writing a [syscmd gzip] emulation in Tcl as
gzip creates a different header.
