Changes in version 1.13:
Changes in version 1.14:
The detection of bzip2 files with no compressed blocks has been fixed.
(Error introduced in version 1.9).
'zupdate --recursive --destdir=dir' now keeps the file name component
following the last slash in directory arguments;
'../a' recompresses the file ../a/b.gz to dir/a/b.lz, while
'../a/' recompresses the file ../a/b.gz to dir/b.lz.
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, they now try to
compare it with a compressed file of any of the remaining formats if the
corresponding uncompressed file does not exist.
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.
The chapter 'Syntax of command-line arguments' has been added to the manual.

Write recompressed files to another directory, using DIR as base

preceding the last slash (if any) of each FILE specified in the
command line, and then prepending DIR to produce the recompressed file
names.
In recursive mode, if FILE ends with a slash and names a directory, it
is completely replaced with DIR. Therefore, if FILE ends with a slash,
all the files in FILE are recompressed directly into DIR, but if FILE
does not end with a slash, the files in FILE are recompressed into the
subdirectory DIR/`basename( FILE )`. 'FILE/' is thus equivalent to
'FILE/*', but without the danger of exceeding the length limit of the
command line.
For example, 'zupdate -r -d DIR ../a' recompresses the file
'../a/b.gz' to 'DIR/a/b.lz', while 'zupdate -r -d DIR ../a/'
recompresses the same file to 'DIR/b.lz'. Regular files specified in
the command line are recompressed directly into DIR. For example,
'zupdate -d DIR ../a/b.gz' writes the recompressed file to 'DIR/b.lz'.

10 Syntax of command-line arguments
***********************************
POSIX recommends these conventions for command-line arguments.
* A command-line argument is an option if it begins with a hyphen ('-').
* Option names are single alphanumeric characters.
* Certain options require an argument.
* An option and its argument may or may not appear as separate tokens.
(In other words, the whitespace separating them is optional). Thus,
'-o foo' and '-ofoo' are equivalent.
* One or more options without arguments, followed by at most one option
that takes an argument, may follow a hyphen in a single token. Thus,
'-abc' is equivalent to '-a -b -c'.
* Options typically precede other non-option arguments.
* The argument '--' terminates all options; any following arguments are
treated as non-option arguments, even if they begin with a hyphen.
* A token consisting of a single hyphen character is interpreted as an
ordinary non-option argument. By convention, it is used to specify
standard input, standard output, or a file named '-'.
GNU adds "long options" to these conventions:
* A long option consists of two hyphens ('--') followed by a name made
of alphanumeric characters and hyphens. Option names are typically one
to three words long, with hyphens to separate words. Abbreviations can
be used for the long option names as long as the abbreviations are
unique.
* A long option and its argument may or may not appear as separate
tokens. In the latter case they must be separated by an equal sign '='.
Thus, '--foo bar' and '--foo=bar' are equivalent.
The syntax of options with an optional argument is
'-<short_option><argument>' (without whitespace), or
'--<long_option>=<argument>'.

@itemx --destdir=@var{dir}
Write recompressed files to another directory, using @var{dir} as base
directory, instead of writing them in the same directory as the original
files. In recursive mode, this is done by replacing each directory specified
in the command line with @var{dir} to produce the recompressed file names.
For example, @w{@samp{zupdate -r -d @var{dir} ../a}} recompresses a file
named @file{../a/b/c.gz} to @file{@var{dir}/b/c.lz}. Regular files specified
in the command line are recompressed directly into @var{dir}. For example,
@w{@samp{zupdate -d @var{dir} ../a/b/c.gz}} writes the recompressed file to
@file{@var{dir}/c.lz}.
files. This is done by removing the (possibly empty) prefix preceding the
last slash (if any) of each @var{file} specified in the command line, and
then prepending @var{dir} to produce the recompressed file names.
In recursive mode, if @var{file} ends with a slash and names a directory, it
is completely replaced with @var{dir}. Therefore, if @var{file} ends with a
slash, all the files in @var{file} are recompressed directly into @var{dir},
but if @var{file} does not end with a slash, the files in @var{file} are
recompressed into the subdirectory @w{@var{dir}/`basename( @var{file} )`}.
@samp{@var{file/}} is thus equivalent to @samp{@var{file/*}}, but without
the danger of exceeding the length limit of the command line.
For example, @w{@samp{zupdate -r -d @var{dir} ../a}} recompresses the file
@file{../a/b.gz} to @file{@var{dir}/a/b.lz}, while
@w{@samp{zupdate -r -d @var{dir} ../a/}} recompresses the same file to
@file{@var{dir}/b.lz}. Regular files specified in the command line are
recompressed directly into @var{dir}. For example,
@w{@samp{zupdate -d @var{dir} ../a/b.gz}} writes the recompressed file to

@node Argument syntax
@chapter Syntax of command-line arguments
@cindex argument syntax
POSIX recommends these conventions for command-line arguments.
@itemize @bullet
@item A command-line argument is an option if it begins with a hyphen
(@samp{-}).
@item Option names are single alphanumeric characters.
@item Certain options require an argument.
@item An option and its argument may or may not appear as separate tokens.
(In other words, the whitespace separating them is optional).
Thus, @w{@option{-o foo}} and @option{-ofoo} are equivalent.
@item One or more options without arguments, followed by at most one option
that takes an argument, may follow a hyphen in a single token.
Thus, @option{-abc} is equivalent to @w{@option{-a -b -c}}.
@item Options typically precede other non-option arguments.
@item The argument @samp{--} terminates all options; any following arguments
are treated as non-option arguments, even if they begin with a hyphen.
@item A token consisting of a single hyphen character is interpreted as an
ordinary non-option argument. By convention, it is used to specify standard
input, standard output, or a file named @samp{-}.
@end itemize
@noindent
GNU adds @dfn{long options} to these conventions:
@itemize @bullet
@item A long option consists of two hyphens (@samp{--}) followed by a name
made of alphanumeric characters and hyphens. Option names are typically one
to three words long, with hyphens to separate words. Abbreviations can be
used for the long option names as long as the abbreviations are unique.
@item A long option and its argument may or may not appear as separate
tokens. In the latter case they must be separated by an equal sign @samp{=}.
Thus, @w{@option{--foo bar}} and @option{--foo=bar} are equivalent.
@end itemize
@noindent
The syntax of options with an optional argument is
@option{-<short_option><argument>} (without whitespace), or
@option{--<long_option>=<argument>}.
