Zutils 1.4-pre1 is ready for testing here
The sha1sum is:
Please, test it and report any bugs you find.
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, 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.

Changes in this version:
* The option "--format" has been renamed to "-O, --force-format".
* Option "-M, --format=<list>" now excludes from automatic search the
formats not listed in the comma-separated <list>. This change introduces
a backward incompatibility with previous versions of zutils.
Suggestions about the '--format' option and about the convenience of
including or excluding other files (implementing '--include' and
'--exclude' options like the ones of GNU grep for example) are welcome.
* The targets "install-compress", "install-strip-compress",
"install-info-compress" and "install-man-compress" have been added to
Antonio Diaz, zutils author and maintainer.
