I am pleased to announce the release of zutils 1.6.
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
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.
Zutils uses external compressors. 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. If the 'gpg --verify' command fails because
you don't have the required public key, then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 8FE99503132D7742
Changes in version 1.6:
* zcmp now accepts the 'B' suffix in the values of '--ignore-initial'
as in '--ignore-initial=1kB:1234B'.
* The input filename is now shown in more error messages.
