+Creates a variable for A/B testing, for example:
+<example>
+split_clients "${remote_addr}AAA" $variant {
+               0.5%               .one;
+               2.0%               .two;
+               *                  "";
+}
+</example>
+The value of the original string is hashed using MurmurHash2.
+In the example given, hash values from 0 to 21474836 (0.5%)
+correspond to the <var>$variant</var> variable taking the
+value <literal>".one"</literal>,
+hash values from 21474837 to 107374182 (2%) correspond to
+the value <literal>".two"</literal>,
+and hash values from 107374183 to 4294967297 correspond to
+the value <literal>""</literal>.
