+
+SYNOPSIS
+    xor(x1, x2, ...)
+

+    x1, x2, ...	integer
+
+    return	integer
+
+DESCRIPTION
+    Compute the bitwise exclusive or of a set of integers.
+
+    For one argument xor(x1) returns x1.  For two arguments,
+    xor(x1,x2) returns the bitwise exclusive or of x1 and x2.
+    For each bit pair:
+
+	0 0 xor returns 0
+	0 1 xor returns 1
+	1 0 xor returns 1
+	1 1 xor returns 0
+
+    For more than two arguments, xor(x1,x2,x3, ..., xn) returns:
+
+	xor(...xor(xor(x1,x2), x3), ... xn)
+
+EXAMPLE
+    > print xor(2), xor(5, 3, -7, 2, 9)
