"""

Prints to stdout the package names that have overlay changes between

current_overlays.txt and previous_overlays.txt.

Usage: diff_package_overlays.py <current_packages.txt> <current_overlays.txt> <previous_overlays.txt>

current_packages.txt contains all package names separated by space in the current build.

This script modfies current_packages.txt if necessary: if there is a package in

previous_overlays.txt but absent from current_packages.txt, we copy that line

from previous_overlays.txt over to current_packages.txt. Usually that means we

just don't care that package in the current build (for example we are switching

from a full build to a partial build with mm/mmm), and we should carry on the

previous overlay config so current_overlays.txt always reflects the current

status of the entire tree.

Format of current_overlays.txt and previous_overlays.txt:

  <package_name> <resource_overlay> [resource_overlay ...]

  <package_name> <resource_overlay> [resource_overlay ...]

  ...
