# Hack:
# protoc generated files contain imports like:
#   "from google.protobuf.xxx import yyy"
# However, the sources files of the python runtime are not directly under
# "google/protobuf" (they are under python/google/protobuf).  We workaround
# this by copying runtime source files into the desired location to workaround
# the import issue. Ideally py_library should support something similiar to the
# "include" attribute in cc_library to inject the PYTHON_PATH for all libraries
# that depend on the target.
#
# If you use python protobuf as a third_party library in your bazel managed
# project:
# 1) Please import the whole package to //google/protobuf in your
# project. Otherwise, bazel disallows generated files out of the current
# package, thus we won't be able to copy protobuf runtime files into
# //google/protobuf/.
# 2) The runtime also requires "six" for Python2/3 compatibility, please see the
# WORKSPACE file and bind "six" to your workspace as well.
