format is itself portable across platforms.  Unlike the LZW compression method
used in Unix compress(1) and in the GIF image format, the compression method
currently used in zlib essentially never expands the data. (LZW can double or
triple the file size in extreme cases.)  zlib's memory footprint is also
independent of the input data and can be reduced, if necessary, at some cost
in compression.")

All blocks are packed to minimize the data overhead, and block sizes of
between 4K and 1M are supported.  It is intended to be used for archival use,
for live media, and for embedded systems where low overhead is needed.

The squashfs-tools-ng package offers alternative tooling to create and extract
such file systems.  It is not based on the older squashfs-tools package and
its tools have different names:

@enumerate
@item @command{gensquashfs} produces SquashFS images from a directory or
@command{gen_init_cpio}-like file listings and can generate SELinux labels.
@item @command{rdsquashfs} inspects and unpacks SquashFS images.
@item @command{sqfs2tar} and @command{tar2sqfs} convert between SquashFS and
tarballs.
@item @command{sqfsdiff} compares the contents of two SquashFS images.
@end enumerate

These commands are largely command-line wrappers around the included
@code{libsquashfs} library that intends to make SquashFS available to other
applications as an embeddable, extensible archive format.

Both the library and tools operate deterministically: same input will produce
byte-for-byte identical output.")

    (description
     "Zip is a compression and file packaging/archive utility.  Zip is useful
for packaging a set of files for distribution, for archiving files, and for
saving disk space by temporarily compressing unused files or directories.
Zip puts one or more compressed files into a single ZIP archive, along with
information about the files (name, path, date, time of last modification,
protection, and check information to verify file integrity).  An entire
directory structure can be packed into a ZIP archive with a single command.

Zip has one compression method (deflation) and can also store files without
compression.  Zip automatically chooses the better of the two for each file.
Compression ratios of 2:1 to 3:1 are common for text files.")

@command{ztest} tests the integrity of supported compressed files.
@command{zupdate} recompresses files with lzip, similar to gzip's
@command{znew}.

Supported compression formats are bzip2, gzip, lzip, and xz.  Zutils uses
external compressors: the compressor to be used for each format is configurable

can append files to the end of such compressed archives.")
