I see a lot of deprecation warnings in the crypto module with the
latest release of Erlang. (crypto:sha_mac/2 -> crypto:hmac/3,
crypto_md5_* -> crypto:hash/2 ...) .

Is there a way to handle this changes at compile time to use latest
functions when possible and old functions in legacy releases?

With the help of rebar I did such change:


But I'm wondering if there is a better solution. Also able to handle
more legacy versions.

Any idea?
