# This is a script used by the typescript flatbuffer bazel rules to compile
# a flatbuffer schema (.fbs file) to typescript and then use esbuild to
# generate a single output.
# Note: This relies on parsing the stdout of flatc to figure out how to
# run esbuild.
# --- begin runfiles.bash initialization v2 ---
# Copy-pasted from the Bazel Bash runfiles library v2.
