# Shutter release builder.
# Bumps patch version in pubspec.yaml, builds split-per-ABI release APKs,
# renames arm64-v8a as shutter-<ver>.apk, archives prior v8a builds,
# stores other ABIs alongside.
#
# Usage:
#   .\build.ps1              # bump patch, build, archive
#   .\build.ps1 -NoBump      # rebuild current version (overwrites)
#   .\build.ps1 -Bump minor  # bump minor (resets patch)
#   .\build.ps1 -Bump major  # bump major (resets minor + patch)
