The WrapText(text, width) calling sequence attempts to wrap long lines in the string text to a specified width width by inserting line breaks in the text to break lines longer than width bytes. Line breaks inserted by the command are inserted between ``words'' in the input; a word is defined to be a maximal contiguous sequence of non-space characters. Any word longer than width is not broken, but appears on a line by itself in the output.

The width argument is optional, and is equal to  by default. It must be a positive integer.

Tab characters in the input string text are expanded, by default.  An option of the form  or  may be passed to control tab expansion, where n is a positive integer and loi is a strictly increasing sequence of positive integers.  See StringTools[ExpandTabs].
