Zutils 是一组用来处理压缩文件的工具集，支持的压缩档包括：gzip, bzip2, lzip, and xz. 当前版本提供的命令有：zcat, zcmp, zdiff, and zgrep.
Zutils 1.0 改进记录：
A new "--format" option has been added to all utilities.
Zgrep no longer 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 was used, has been fixed.
Decompressors are now invoked without the "-q" option except when explicitly requested.
Quote characters in messages have been changed as advised by GNU Coding Standards.
"configure" now accepts options with a separate argument
