//! PSBT bitcoin library, providing all PSBT functionality from [`bitcoin`]
//! library, plus
//! - constructor, supporting miniscript-based descriptors, input descriptors,
//!   all sighash types, spendings from P2C, S2C-tweaked inputs ([`construct`]);
//! - advanced signer, supporting pre-segwit, bare and nested segwit v0, taproot
//!   key and path spendings, different forms of tweaks & commitments, all
//!   sighash types ([`sign`]);
//! - commitment-related features: managing tapret-, P2C and S2C-related
//!   proprietary keys;
//! - utility methods for fee computing, lexicographic reordering etc;
//! - command-line utility for editing PSBT data (WIP).
