## What it is
A small JavaScript library that enables multiline strings via block comments inside anonymous function calls, with an optional stripIndent helper. It is deprecated and superseded by ES2015 template literals.

## Use cases
- write multiline strings without concatenation or array join
- define CLI help output text
- store test fixtures as readable multiline text
- embed multi-line database queries in code
- print multi-line CLI welcome messages

## When to choose
- maintaining legacy JavaScript codebases that already depend on it
- targeting pre-ES2015 environments without template literal support

## When to avoid
- starting any new project - use ES2015 template literals instead
- performance-critical string building
- modern Node.js or browser environments

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools
