## What it is
SAD (Space Age seD) is a Rust CLI tool for batch search-and-replace across files, showing a diff preview of proposed changes before committing them. It integrates with fzf for interactive selective replacement and supports diff colorizers like delta and diff-so-fancy.

## Use cases
- batch find and replace across many files
- preview sed-like edits as a diff before applying
- interactively select which replacements to apply with fzf
- regex-based bulk text editing from the command line
- safe alternative to sed for large refactors

## When to choose
- you want to review diffs before committing bulk edits
- you need interactive, selective replacement across a codebase
- you prefer a modern Rust tool over sed's in-place editing

## When to avoid
- you need a simple one-liner in-place edit where sed suffices
- you don't want to install fzf for the interactive experience
- you need streaming edits on non-file input
