# Example usage (assumes Posix-standard shell, git installed):
#
# git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
# export PATH="${PWD}/depot_tools:${PATH}"
# git clone https://skia.googlesource.com/skia
# cd skia
# bin/sync-and-gyp && ninja -C out/Debug
# out/Debug/dm
#
# Once changes are made to DEPS or gyp/ or the source, recompile Skia with:
#
# ${skiadir}/bin/sync-and-gyp && ninja -C ${skiadir}/out/Debug
