Idea 5.0 - What all can we put in idea.exe.vmoptions

In ]]>/bin/ there's a file called idea.exe.vmoptions. This appears to replaced the idea.lax file in Idea 4.x.

By default the file contained:

I figured out that Xms is the amount of startup memory and Xmx is the max memory, so I upped those. What is XX:MaxPermSize and ea?

Also, what other useful things can we put in here?

-ea stands for Enable Assertions.
-XX:MaxPermSize - 1.5 JRE specific option that controls Permanent Generation
max size.
