# A macro to make rules to copy all newer files in a directory tree matching an

# Designed after copy_headers.make: Create a rule to copy each file;
# copy-one-file defines the actual rule.
# $(1): source directory tree root
# $(2): destination directory tree root
# $(3): list variable to append destination files to
# $(4): optional find(1) arguments

# Install all the files needed to build the pndk.
# We build three versions of the pndk
# (1) The full version, with source.
# (2) The full version, without source.
# (3) A JNI-only version, with source.
#
# We make five sets of trees:
# (A) Common files used in all versions of the pndk
# (B) Common files used in the full versions of the pndk
# (C) Files used in the standard pndk (no source files included)
# (D) Files used in both the JNI-only and full-with-source version
# (E) Files used in just the full-with-source version
#
# Each pndk version is created by combining the appropriate trees:
#
# (A) (B) (C) (D) (E)
# (1) yes yes yes yes
# (2) yes yes yes
# (3) yes yes
#
# Source is provided for partners who want to recompile our libraries for optimization.
# The JNI-only version is provided for partners that want to create shared
# libraries that can be packaged with APK files and called from Java code.
