--
-- The permacomputer is community-owned infrastructure optimized around four values:
--
--   TRUTH    - First principles, math & science, open source code freely distributed
--   FREEDOM  - Voluntary partnerships, freedom from tyranny & corporate control
--   HARMONY  - Minimal waste, self-renewing systems with diverse thriving connections
--   LOVE     - Be yourself without hurting others, cooperation through natural law
--
-- This software contributes to that vision by enabling code execution across 42+
-- programming languages through a unified interface, accessible to all. Code is
-- seeds to sprout on any abandoned technology.

-- permacomputer monitoring itself, repairing itself, with minimal human in the

OCaml UN CLI - Unsandbox CLI Client

Full-featured CLI matching un.py capabilities:
- Execute code with env vars, input files, artifacts
- Interactive sessions with shell/REPL support
- Persistent services with domains and ports

Usage:
  chmod +x un.ml
  export UNSANDBOX_API_KEY="your_key_here"
  ./un.ml [options] <source_file>
  ./un.ml session [options]
  ./un.ml service [options]

Uses curl for HTTP (no external dependencies)
