[Zutils-bug] Zutils 1.13 released

[Antonio Diaz Diaz]

I am pleased to announce the release of zutils 1.13.

Zutils is a collection of utilities able to process any combination of 
compressed and uncompressed files transparently. If any file given, 
including standard input, is compressed, its decompressed content is used. 
Compressed files are decompressed on the fly; no temporary files are 
created. Data format is detected by its identifier string (magic bytes), not 
by the file name extension.

These utilities are not wrapper scripts but safer and more efficient C++ 
programs. In particular the option '--recursive' is very efficient in those 
utilities supporting it.

The utilities provided are zcat, zcmp, zdiff, zgrep, ztest, and zupdate.
The formats supported are bzip2, gzip, lzip, xz, and zstd.
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 --recv-keys 8FE99503132D7742

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742


Changes in version 1.13:

  * The detection of bzip2 files with no compressed blocks has been fixed. 
(Error introduced in version 1.9).

  * When zcat, zcmp, zdiff, or zgrep need to try compressed file names, 
gzip (.gz) is now tried before bzip2 (.bz2).

  * When only one compressed file is passed to zcmp or zdiff and the 
corresponding uncompressed file does not exist, they now try to compare the 
file with a compressed file of any of the remaining formats.

  * zcmp now reports EOF on empty file like GNU cmp:
    "zcmp: EOF on FILE which is empty".

  * File diagnostics in zupdate have been reformatted as 'PROGRAM: FILE: 
MESSAGE'.

  * The variable MAKEINFO has been added to configure and Makefile.in.
