Release Notes: The zutils executable has been removed. All utilities are now independent executables. The new option "-k, --keep" has been added to zupdate. The exit status of zgrep should now be identical to that of grep in case of error.
Release Notes: The new utility zupdate, which recompresses bzip2, gzip, and xz files to lzip format, has been added.
Release Notes: 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.
Release Notes: The output of "zgrep -L" has been fixed (it behaved like "zgrep -l").
Release Notes: Decompressors are now invoked without the "-q" option unless explicitly requested, as some simplified implementations do not accept it.
Release Notes: Zgrep now shows file names by default when "--recursive" is selected. A deadlock in zcmp, which happens when the "-n" option was used, has been fixed.
Release Notes: Zgrep no longer prefixes the file name to the output by default when searching one file. A portability issue with Solaris 9 has been (hopefully) fixed.
Release Notes: This release adds minor fixes. The new option "--format", which forces the use of a given compression format, has been added to all utilities. The target "install-bin" has been added to the Makefile.
Release Notes: The configure option "--datadir" has been renamed to "--datarootdir" to follow GNU Standards.
Release Notes: Quote characters in messages have been changed as advised by GNU Coding Standards. Information has been added to the INSTALL file about how to install zutils along with GNU gzip.
