+A simple example of transferring SOL between two system accounts. You can transfer SOL between many types of accounts, not just system accounts (owned by the System Program).
+
+One thing to note here is that we are generating a brand new keypair in the test - both for `native` and `anchor`. The act of transferring SOL to the new keypair's account will initialize it as a default system account (hence the `/// CHECK` above it in the `anchor` example).
