# If you want touse a custom linker with Cargo, Cargo requires that you
# specify it in Cargo.toml or via the matching environment variable.
# Passing extra options to the linker is possible with Cargo via
# RUSTFLAGS='-C link-args', but testing showed that doing this reliably
# was difficult.

# Our solution to these problems istouse this wrapper script. We pass
