Indicates that the output should be split into lines of no more than

this must be in the range 3 to 85 due to limitations in the encoding.
Indicates the maximum number of characters to produce for each encoded line.
The valid range is 5 to 85. Line lengths outside that range cannot be
accommodated by the encoding format. The default value is 61.

\fIcharacter\fR should be used to separate lines. By default, this is a

Indicates the character(s) to use to mark the end of each encoded line.
Acceptable values are a sequence of zero or more characters from the
set { \\x09 (TAB), \\x0B (VT), \\x0C (FF), \\x0D (CR) } followed
by zero or one newline \\x0A (LF). Any other values are rejected because
they would generate encoded text that could not be decoded. The default value
is a single newline.

Instructs the decoder to throw an error if it encounters anything
