# Description:
#  Port of various google3 libraries and utilities. In google3, blaze allows
#  building two variants controlled by the --define=darwinn_portable flag.
#   --define=darwinn_portable=0 (default) :
#    Port directory points to google3. (DARWINN_PORT_GOOGLE3 is defined.)
#   --define=darwinn_portable=1 :
#    Port directory points to default/ (DARWINN_PORT_DEFAULT is defined.)
# Android:
#  For compiling against Android NDK (with google3 blaze) both above configurations
#  will work.
#  For compiling as part of Android system however, DARWINN_PORT_ANDROID
#  must be defined as part of the Android build system.
