  20 # The `ndk-build` tool from the Android NDK must be in PATH before
  21 # invoking this tool. It will be used to guess the path to the NDK.
  22 #
  23 # Alternatively, you may define a custom path to the NDK by setting
  24 # `ANDROID_NDK`.
  25 #
  26 # The source package should be downloaded and compiled only once.
  27 # If the working directory is cleared, the cached version will be lost.
  28 # On test servers, which clear the working directory frequently,
  29 # it may be a good idea to use a local version of the source packages.
  30 # To do so, download the following two packages and put them in your HOME directory.
  31 # * http://www.hboehm.info/gc/gc_source/gc-7.4.0.tar.gz
