+FUNCTION
+<<puts>>---write a character string
+
+INDEX
+	puts
+INDEX
+	_puts_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int puts(const char *<[s]>);
+
+	int _puts_r(void *<[reent]>, const char *<[s]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int puts(<[s]>)
+	char *<[s]>;
+
+	int _puts_r(<[reent]>, <[s]>)
+	char *<[reent]>;
+	char *<[s]>;
+
+DESCRIPTION
+<<puts>> writes the string at <[s]> (followed by a newline, instead of
+the trailing null) to the standard output stream.
+
+The alternate function <<_puts_r>> is a reentrant version.  The extra
+argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+If successful, the result is a nonnegative integer; otherwise, the
+result is <<EOF>>.
+
+PORTABILITY
+ANSI C requires <<puts>>, but does not specify that the result on
+success must be <<0>>; any non-negative value is permitted.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.  */
