I am pleased to announce the release of zutils 1.1.
Zutils is a collection of utilities able to deal with 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
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 provided utilities are zcat, zcmp, zdiff, zgrep and ztest.
The supported formats are bzip2, gzip, lzip and xz.
The compressor to be used for each format is configurable at runtime.

This release is also GPG signed. You can download the signature by
appending ".sig" to the URL.
Changes in version 1.1:
* The new options "--bz2", "--gz", "--lz" and "--xz" have been added
to all utilities.
* Zutils now provides the runtime configuration file "zutilsrc",
which allows the user change the compressor to be used for each format.
* The checking of the exit status of compressors has been improved.
* The use of "decompressed" and "uncompressed" in the documentation
has been revised.
