Many commands that perform file input/output, by default,
allow automatic conversion of tagged files. Some of these commands
can disable automatic conversion using the -B option.
The explicit use of the -B option on the
command overrides any automatic conversion as well as any text conversion
indicated by the _TEXT_CONV environment variable. 
The -B option applies to
the input text file that is processed by the command. Other files
used by the command, such as a file list or configuration information,
are not affected by the -B option. When
a command allows the use of the standard input (stdin) in place of
the input text file, the -B option will
disable automatic conversion of the standard input (stdin) if it is
not associated with a terminal.
