I am pleased to announce the release of zutils 1.0.
Zutils is a collection of utilities able to deal with any combination of
compressed and non-compressed 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 and ztest.
The supported formats are bzip2, gzip, lzip and xz.

The md5sums are:
Changes in version 1.0:
* The new option "--format" has been added to all utilities.
* Zgrep no more prefixes the file name to the output by default when
searching one file and "--recursive" has not been selected.
* The output of "zgrep -L" has been fixed (it behaved like "zgrep -l").
* A deadlock in zcmp, which happens when the "-n" option is used, has
* Decompressors are now invoked without the "-q" option except if
explicitly requested, as some simplified implementations do not accept it.
* Quote characters in messages have been changed as advised by GNU
* "configure" now accepts options with a separate argument.
* Configure option "--datadir" has been renamed to "--datarootdir" to
follow GNU Standards.
* The target "install-bin" has been added to the Makefile.
* Information has been added to the INSTALL file about how to install
zutils along with GNU gzip.
