# Helper script for setting environment variables required for Bazel/Soong

|

# export BAZEL_PATH=[some_bazel_path] && source bazelenv.sh
|
|
#
|
|
# If BAZEL_PATH is not set, `which bazel` will be used
|
|
# to locate the appropriate bazel to use.
|
|
|

|
# Function to find top of the source tree (if $TOP isn't set) by walking up the
|
|
# tree.
