use on virtually any computer hardware and operating system.  The zlib data
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.")

compressed data format (.lz).  It can test the integrity of lzip files, extract
data from damaged ones, and repair most files with small errors (up to one
single-byte error per member) entirely.

Lziprecover is not a replacement for regular backups, but a last line of defence
when even the backups are corrupt.  It can recover files by merging the good
parts of two or more damaged copies, such as can be easily produced by running
@command{ddrescue} on a failing device.

This package also includes @command{unzcrash}, a tool to test the robustness of
decompressors when faced with corrupted input.")

     "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.")

    (description
     "Zutils is a collection of utilities able to process any combination of
compressed and uncompressed files transparently.  If any given file, including
standard input, is compressed, its decompressed content is used instead.

@command{zcat}, @command{zcmp}, @command{zdiff}, and @command{zgrep} are
improved replacements for the shell scripts provided by GNU gzip.
@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
at run time, and must be installed separately.")
