The \width command specifies the width of the page that will be used for
printing the file. The format is:
\width{uu}
where "uu" is the unit of measurement in any valid TeX measurement (pt, pc, in,
etc.) or number of 10-pitch characters. The default page width is 8.5 inches,
or \width{8.5IN}. This command may only appear at the beginning of the TeX
input file before any actual text is entered.
