|
|
//!
|
|
//! A simple example of a FRAME pezpallet demonstrating

|
//! the ease of requirements for a pezpallet in dev mode.

//!
|
|
//! Run `cargo doc --package pezpallet-dev-mode --open` to view this pezpallet's documentation.
|
|
//!
|
|
//! **Dev mode is not meant to be used in production.**
