## What it is
A Bash function that runs shell tasks in parallel with dependency ordering and pretty terminal output. It is a single-file shell library sourced into scripts.

## Use cases
- run shell tasks in parallel
- run bash commands concurrently with pretty output
- define task dependencies in bash scripts
- run tasks sequentially or in stages from the terminal
- parallelize build or deployment steps in shell

## When to choose
- you want parallel task execution in pure Bash with no dependencies
- you need simple dependency ordering between shell tasks
- you want readable status output for long-running shell jobs

## When to avoid
- you need a full workflow engine with retries, scheduling, or distributed execution
- your tasks are in Python or another language with better-native parallelism
- you need Windows support

- artifact type: library
