Please note: we're not going to describe something as painful as the pxml file here :P
file structure
a .dbp files is composed of 2 concatenated files :
- a squashfs file
- an *uncompressed* zip
The squashfs part contain your application(s) and everything it might need to run.
The zip part contain the meta-data related to the DBP.
