# Strip the PRI split configuration from a MakePri-generated priconfig.xml.
#
# `MakePri.exe createconfig` emits a <packaging> section telling `MakePri.exe new` to
# split resource candidates into separate resource packages (resources.language-*.pri,
# resources.scale-*.pri, ...), leaving the main resources.pri with default-context
# candidates only. A monolithic MSIX package loads nothing but the resources.pri at its
# package root, so any split dimension - autoResourcePackage qualifiers (Language, Scale,
# DXFeatureLevel, ...) as well as manual resourcePackage entries - would strip its
# candidates from the shipped package, e.g. every non-default UI language would silently
# fall back to the source language.
#
# This script therefore removes the whole <packaging> element. The schema declares it
# optional, and leaving an empty one behind would make MakePri warn about a missing
# packaging mode. The file is rewritten in place as UTF-8 without BOM.
#
# Usage (the Windows CI calls it between `MakePri.exe createconfig` and `MakePri.exe new`):
#   pwsh -NoProfile -ExecutionPolicy Bypass -File strip-priconfig-packaging-node.ps1 -Path priconfig.xml -Verbose
