.SH DESCRIPTION
-Zcat \- Cat wrapper for compressed files.
-.PP
-Zcat is a wrapper script around the cat command that allows transparent
-concatenation of any combination of compressed and non\-compressed files.
-If any given file is compressed, its uncompressed content is used. If a
-given file does not exist, zcat tries the compressed file names
+Zcat copies each given file ("\-" means standard input), to standard
+output. If any given file is compressed, its uncompressed content is
+used. If a given file does not exist, and its name does not end with one
+of the known extensions, zcat tries the compressed file names
corresponding to the supported compressors. If no files are specified,
data is read from standard input, decompressed if needed, and sent to
-stdout. Data read from standard input must be of the same type; all
-uncompressed or all compressed with the same compressor.
+standard output. Data read from standard input must be of the same type;
+all uncompressed or all compressed with the same compressor.
The supported compressors are bzip2, gzip, lzip and xz.
.PP
-CAT_OPTIONS are passed directly to cat.
-The exit status from cat is preserved.
+Exit status is 0 if no errors occurred, 1 otherwise.
