Zcat copies each given file ("\-" means standard input), to standard
output. If any given file is compressed, its decompressed 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 formats. If no files are specified,
data is read from standard input, decompressed if needed, and sent to
standard output. Data read from standard input must be of the same type;
all uncompressed or all in the same compression format.
