# License Picker

Open source license reference — SPDX identifiers, permissive vs copyleft comparison, license compatibility matrix, patent clauses, and compliance scanning tools. No API keys or credentials required — outputs reference documentation only.

## Commands

| Command | Description |
|---------|-------------|
| `intro` | Permissive vs copyleft, license types |
| `standards` | SPDX identifiers, OSI/FSF, compatibility |
| `troubleshooting` | Conflicts, dual licensing, CLA issues |
| `performance` | Scanning tools: FOSSA, Snyk, scancode |
| `security` | Patents, indemnification, AGPL/SaaS risks |
| `migration` | Proprietary to open source, relicensing |
| `cheatsheet` | License comparison table, decision guide |
| `faq` | Commercial use, GPL enforcement, choosing |

## Output Format

All commands output plain-text reference documentation via heredoc. No external API calls, no credentials needed, no network access.
