+ "for each file writes a line containing the number of newlines, "
+ "\aword\as, and bytes contained in each file followed by the "
+ "file name to standard output in that order. A \aword\a is "
+ "defined to be a non-zero length string delimited by \bisspace\b(3) "
+ "characters.]"
+"[+?If more than one file is specified, \bwc\b writes a total count "
+ "for all of the named files with \btotal\b written instead "
+ "of the file name.]"
+"[+?By default, \bwc\b writes all three counts. Options can specified "
+ "so that only certain counts are written. The options \b-c\b "
+ "and \b-m\b are mutually exclusive.]"
+"[+?If no \afile\a is given, or if the \afile\a is \b-\b, \bwc\b "
+ "reads from standard input and no filename is written to standard "
+ "output. The start of the file is defined as the current offset.]"
+"[l:lines?List the line counts.]"
+"[w:words?List the word counts.]"
+"[c:bytes|chars:chars?List the byte counts.]"
+"[m|C:multibyte-chars?List the character counts.]"
+"[q:quiet?Suppress invalid multibyte character warnings.]"
+"[L:longest-line|max-line-length?List the longest line length.]"
