[p2-dev] Unzip install action problems

[Deric Panet-Raymond <deric@xxxxxxxxxxxxxxxxx>]

I'm attempting to replace a cumbersome package upgrade feature which 
uses a custom touchpoint to execute a platform specific binary installer 
by using the built in unzip touchpoint.  I've attempted to build a 
plugin with the zip file added and a feature which has a p2.inf 
containing the following.

instructions.install = 
org.eclipse.equinox.p2.touchpoint.natives.unzip(source: 
${artifact.location}/engine.zip, 
target:${installFolder}/Engine/$version$.$qualifier$);

My first question, how can I debug this install action?  When I run my 
eclipse app with -debug in the .ini file I see some information on the 
console, but nothing shows up during the upgrade process, and my file 
does not appear to be unzipped anywhere.

My Second question, is it possible to access a Path outside of the 
installFolder?  our directory tree of the installed product looks like.

/product
|
---->Documentation
---->Samples
---->Designer
---->Engine

The eclipse app lives in a subdirectory of Designer, I need to unzip the 
contents of my archive into the Engine directory, is this even possible?

Thanks.
