Debugging Javascript custom actions

[installer96]

Is there a way to step through Javascript custom actions? I can't find much documentation or info at all on using Javascript custom actions.

Our Javascript writes to the MSI log so I've just been running the installations over and over and poking through the logs. Being able to step through the Javascript would make my life much easier.

IIRC, It's more or less the same as VBscript custom actions.
