# This script takes a Linux SDK, cleans it and injects the necessary Windows
# binaries needed by the SDK. The script has 2 parts:
# - development/tools/build/path_windows_sdk.sh to process the
#   platform-dependent folders and files.
# - sdk/build/patch_windows_sdk.sh to process folder and files which
#   depend on the sdk.git repo. This file is invoked by the makefile
#   at development/build/tools/windows_sdk.mk.
#
# Input arguments:
# -q = Optional arg to make this silent. Must be given first.
# $1 = Temporary SDK directory, that is the Linux SDK being patched into
#      a Windows one.
# $2 = The out/host/windows directory, which contains the new Windows
#      binaries to use.
# $3 = An optional replacement for $TOPDIR (inherited from the Android
#      build system), which is the top directory where Android is located.

set -e # any error stops the build

# Verbose by default. Use -q to make more silent.
