## Overview

Redact is a utility for hiding secret text on the terminal.

It is designed to work with Markdown syntax.  Inline code (text enclosed in
backticks) and code blocks that are fenced with backticks are hidden.  Note
that inline code that spans multiple lines is not supported, and other types
of code blocks are not hidden.

Text is hidden by displaying it using the same color for the foreground and
background.  When selecting hidden text, it remains hidden in some terminals
and becomes visible in other terminals.

Be sure to test it in your terminal before relying on it.

## CLI
