## What it is
Supercronic is a crontab-compatible job runner designed specifically for container environments. It preserves environment variables, logs to stdout/stderr, and handles SIGTERM/SIGINT gracefully so cron jobs behave correctly inside containers.

## Use cases
- run cron jobs inside docker containers
- schedule periodic tasks in kubernetes pods
- replace system cron in a containerized app
- run scheduled background jobs with container environment variables
- gracefully shut down scheduled jobs on container stop
- log cron job output to container stdout

## When to choose
- you need crontab-style scheduling in Docker or Kubernetes
- you want cron jobs to inherit container environment variables
- you need graceful shutdown of running jobs when the container stops
- you want job output logged to stdout/stderr for container log collection

## When to avoid
- you need traditional multi-user system cron on a server
- you need distributed or persistent job scheduling across many nodes
- you need sub-second scheduling precision or complex workflow dependencies
