 This library can be built for either your native platform or in BPF (used by Solana programs). 
 Use `cargo build` / `cargo test` to build and test natively.
 Use `cargo build-bpf` / `cargo test-bpf` to build in BPF for Solana; these commands require you to have installed the [Solana CLI tools](https://docs.solana.com/cli/install-solana-cli-tools).

-The BPF tests will also run an instruction count program that logs the resource consumption
-of various library functions.
-This program can also be run on its own using `cargo test-bpf --test instruction_count`.
