# This script generates TARGETS file for Buck.
# Buck is a build tool specifying dependencies among different build targets.
# User can pass extra dependencies as a JSON object via command line, and this
# script can include these dependencies in the generate TARGETS file.
# Usage:
# $python3 buckifier/buckify_rocksdb.py
# (This generates a TARGET file without user-specified dependency for unit
# tests.)
# $python3 buckifier/buckify_rocksdb.py \
# '{"fake": {
# "extra_deps": [":test_dep", "//fakes/module:mock1"],
# "extra_compiler_flags": ["-DFOO_BAR", "-Os"]
# }
# }'
# (Generated TARGETS file has test_dep and mock1 as dependencies for RocksDB
# unit tests, and will use the extra_compiler_flags to compile the unit test
# source.)
