I am pleased to announce the release of zutils 1.2.

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 are created.

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, ztest and zupdate.
The supported formats are bzip2, gzip, lzip and xz.
The compressor to be used for each format is configurable at runtime.

Zcat, zcmp, zdiff, and zgrep are improved replacements for the shell scripts provided by GNU gzip. Ztest is unique to zutils. Zupdate is similar to gzip's znew.

This release is also GPG signed. You can download the signature by
appending ".sig" to the URL.

Changes in version 1.2:

* The new utility zupdate, which recompresses bzip2, gzip and xz files to lzip format, has been added.

* The zutils executable has been removed. All utilities are now independent executables.

  * The exit status of zgrep should now be identical to that of grep.

  * "zutils.texinfo" has been renamed to "zutils.texi".
