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. Compressed files are decompressed on the fly; no temporary files
-are created.
+compressed and uncompressed files transparently. If any file given,

These utilities are not wrapper scripts but safer and more efficient C++
-programs. In particular the '--recursive' option is very efficient in

those utilities supporting it.
-The utilities provided are zcat, zcmp, zdiff, zgrep, ztest and zupdate.
-The formats supported are bzip2, gzip, lzip and xz.
-Zutils uses external compressors. The compressor to be used for each
-format is configurable at runtime.

-warning values, making them less reliable back ends for zutils.

of formats in recursive mode and when trying compressed file names:

passed to the corresponding decompressor without verifying their format,
allowing for example the processing of compress'd (.Z) files with gzip:
'zcmp --force-format=gz file.Z file.lz'.
