[news.eclipse.platform.rcp] PDE-Export .product Command line 30+projects

[ron@xxxxxxxxxxxxxxxxx (Ron Brash)]

Hello all,

I am doing an automated RCP export on a daily basis using the export 
utility in the gui.  We have a .product file, which creates a directory, 
and places our plugins and binaries there.  As far as I can tell I haven't 
seen a single howto that shows this type of environment, and we are using 
sdk 3.4 and much of the documentation is 3.1 if it even relates remotely 
to what I want.

I know I can use ant:

C:\workspace\com.company.product>java -cp C:/eclipse-SDK-3.4-win32/eclipse/
plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar 
org.eclipse.core.launcher.Main -data c:\workspace -application 
org.eclipse.ant.core.antRunner build-project

and build project being inside of the build.xml file..... but could 
someone lend me a hand.  

Alot of similar posts receive zero attention, and I'd never seen this on a 
community like Linuxquestions or any php site regardless of how noob of a 
question it might be.  So why the lack of responses?

Our workspace..

project1
project2
project3 all the way to about 30
project 31
-build.properties
-productName.product

and we just export using the product wizardry.  AN example would be great 
describing this sort of thing.
