//! Substrate CLI library.
|
|
//!
|
|
//! This package has two Cargo features:
|
|
//!
|
|
//! - `cli` (default): exposes functions that parse command-line options, then start and run the
|
|
//! node as a CLI application.
|
|
//!
|
|
//! - `browser`: exposes the content of the `browser` module, which consists of exported symbols
|
|
//! that are meant to be passed through the `wasm-bindgen` utility and called from JavaScript.
|
|
//! Despite its name the produced WASM can theoretically also be used from NodeJS, although this
|
|
//! hasn't been tested.
