# This is used by Bazel BUILD rules. The problem it solves is the following:
# In GN builds we want to keep client and host separate. This allows reducing
# the binary size by splitting targets all the way up to the client library
# (libperfetto_client_experimental). In bazel/blaze we fuse everything together
# because handling this split is too complex due to the lack of a
# source_set-equivalent.
