rwmstatus 1.0.0

//! # rwmstatus
//!
//! Status monitor bar binary for the dwm/rwm window manager (or any WM which
//! uses WM_NAME of the X11 root window as its status bar).  It is a direct
//! port of [dwmstatus](https://dwm.suckless.org/status_monitor/) to Rust.
//!
//! This is part of my [Rust Sucks
//! Less](https://wojciechkozlowski.eu/rust-sucks-less/) project to port some
//! of the [suckless.org](https://suckless.org/) programs and tools to Rust, a
//! programming language that sucks less.
