## What it is
rainbarf is a Perl CLI tool that renders CPU/RAM/battery usage as a colored chart bar for the tmux (or GNU screen) status line. It color-codes CPU history by memory allocation state and optionally shows battery charge.

## Use cases
- show cpu and memory usage in tmux status bar
- display battery charge indicator in terminal
- fancy resource usage chart for tmux status line
- monitor system resources from the command line
- customize tmux powerline status widget
- color-coded memory allocation chart in terminal

## When to choose
- you use tmux or GNU screen and want resource stats in the status line
- you want a lightweight, scriptable CLI widget instead of a GUI dashboard like Rainmeter
- you want battery and memory state shown with color coding

## When to avoid
- you need a full system monitoring dashboard with alerts or history persistence
- you don't use tmux, GNU screen, or a compatible terminal prompt
- you need monitoring across remote servers or with notification/alerting features
