-"[+NAME?cmp - compare two files]"
-"[+DESCRIPTION?\bcmp\b compares two files \afile1\a and \afile2\a. "
- "\bcmp\b writes no output if the files are the same. By default, "
- "if the files differ, the byte and line number at which the "
- "first difference occurred are written to standard output. Bytes "
- "and lines are numbered beginning with 1.]"
-"[+?If \askip1\a or \askip2\a are specified, or the \b-i\b option is "
- "specified, initial bytes of the corresponding file are skipped "
- "before beginning the compare. The skip values are in bytes or "
- "can have a suffix of \bk\b for kilobytes or \bm\b for megabytes.]"
-"[+?If either \afile1\a or \afiles2\a is \b-\b, \bcmp\b "
- "uses standard input starting at the current location.]"
-"[c:print-chars?Writes control characters as a \b^\b followed by a letter of "
- "the alphabet and precede characters that have the high bit set with "
- "\bM-\b as with \bcat\b(1).]"
-"[i:ignore-initial]#[skip:=0?Sets default skip values for the operands "
- "\askip1\a and \askip2\a to \askip\a.]"
-"[l:verbose?Write the decimal byte number and the differing bytes (in octal) "
- "for each difference.]"
-"[s:quiet|silent?Write nothing for differing files; return non-zero "
- "exit status only.] ]"
-"\n"
-"\nfile1 file2 [skip1 [skip2]]\n"
-"\n"
-"[+EXIT STATUS?]{"
- "[+0?The files or portions compared are identical.]"
- "[+1?The files are different.]"
- "[+>1?An error occurred.]"
