How to add two custom applications in newprods.txt file

Hi everyone, 

I'm following the process descripted in Creating a Custom Application in Oracle E-Business Suite Release 12.1.3 and above (Doc ID 1577707.1)

This process talks about how to add a new custom application trough the configuration of 3 files: izuprod.txt, izterr.txt and newprods.txt.

The two first ones has no problem due you have to change the filename, but what about the third one? How to add a second custom application inside of this file? I imagine could be something like this. I hope you can help me with this:

//Just one custom app
product=xxmz
base_product_top= *APPL_TOP*
