# Basic usage
node dist/index.js input.js > output.js

# With target token budget (default: 2,000,000)
node dist/index.js --target-tokens 500000 input.js > output.js

# Minimal obfuscation (small output)
node dist/index.js --target-tokens 10000 input.js > output.js

# Maximum bloat (10M tokens)
node dist/index.js --target-tokens 10000000 input.js > output.js

# Using environment variable
INPUT_FILE=input.js node dist/index.js > output.js

# Help
node dist/index.js --help
