how to include external jar file using PIG

When I run a mapreduce job using hadoop command, I use -libjars to setup my jar to the cache and the classpath. How to do something like this in PIG?

An extension to zsxwing's answer.
You can also specify multiple jar paths as 

pig -Dpig.additional.jars="/local/path/1/*:/local/path/2/*"

There are two ways to add external jars to Pig environment.

  1. Use "-Dpig.additional.jars" to start Pig

    pig -Dpig.additional.jars=/local/path/to/your.jar

  2. Use "register" command in Pig scripts or grunt

    register /local/path/to/your.jar;

You can use any one according to your requirement.
