+<div class="block">Filter function which asserts that a value is true.
+
+ <p>
+ Unfortunately, the Pig interpreter doesn't recognize boolean expressions nested as function
+ arguments, so this uses C-style booleans.  That is, the first argument should be
+ an integer.  0 is interpreted as "false", and anything else is considered "true".
+ The function will cause the Pig script to fail if a "false" value is encountered.
+ </p>
+
+ <p>
+ There is a unary and a binary version. The unary version just takes a boolean, and throws out a generic exception message when the
+ assertion is violated.  The binary version takes a String as a second argument and throws that out when the assertion
+ is violated.
+ </p>

+ Example:
+ <pre>
+ <code>FILTER members BY AssertUDF( (member_id &gt;= 0 ? 1 : 0), 'Doh! Some member ID is negative.' );
