3//! An upgradeable BPF loader native program.
4//!
5//! The upgradeable BPF loader is responsible for deploying, upgrading, and
6//! executing BPF programs. The upgradeable loader allows a program's authority
7//! to update the program at any time. This ability breaks the "code is law"
8//! contract that once a program is on-chain it is immutable. Because of this,
9//! care should be taken before executing upgradeable programs which still have
10//! a functioning authority. For more information refer to the
11//! [`instruction`] module.
12//!
13//! The `solana program deploy` CLI command uses the
14//! upgradeable BPF loader. Calling `solana program deploy --final` deploys a
15//! program that cannot be upgraded, but it does so by revoking the authority to
16//! upgrade, not by using the non-upgradeable loader.
