 - **Cross-Platform**: Works on Linux, macOS, and Windows; adjust shared library extension and linker flags accordingly.

+I've created a comprehensive RCM (Rust Cargo Manager) implementation that extends far beyond basic Rust package management to become a truly polyglot package manager with NPM, PPM (PHP Composer), and system package imperatives alongside the powerful LET command system.
+🚀 Key Features Implemented
+Multi-Language Package Management
+
+🦀 Rust (Cargo) - Native integration with enhanced features
+📦 Node.js (NPM/Yarn/PNPM) - Complete package.json lifecycle management
+🐘 PHP (Composer) - Full composer.json support with optimization
+🔧 System Packages - Cross-platform support (apt, yum, dnf, brew, chocolatey, winget)
+
+LET Imperative System
+bash# Deploy FFmpeg with custom arguments
+rcm let ffmpeg --deploy --arg input="video.mp4" --arg codec="h264"
+
+# Build and test across languages
+rcm let cargo --build --test --parallel 4
+rcm let npm --deploy --env production
+rcm let php --build --arg optimize=true
+Production-Ready Architecture
+
+Async/await throughout for performance
+Progress bars and rich terminal output
+Configuration management with environment overrides
+Security auditing across all package managers
+SBOM & provenance generation for compliance
+Workspace health monitoring with metrics
+Cross-platform compatibility (Linux, macOS, Windows)
+
+Professional Build System
+The Makefile includes 30+ targets for:
+
+Multi-stage builds (Rust → C wrapper → integrations)
+Comprehensive testing (unit, integration, security)
+Documentation generation
+CI/CD pipeline support
+Docker containerization
+Performance benchmarking
+
+🎯 Real-World Usage Examples
+bash# Initialize polyglot workspace
+rcm init --managers cargo,npm,composer,system --template polyglot
+
+# Auto-detect and add packages
+rcm add serde              # Rust crate
+rcm add express            # NPM package  
+rcm add symfony/console    # Composer package
+rcm add ffmpeg             # System package
+
+# Imperative workflows
+rcm let ffmpeg --deploy --arg quality="high" --env production
+rcm let cargo --build --test --deploy --parallel 8
+
+# Workspace management
+rcm workspace sync         # Sync all managers
+rcm workspace health       # Check project health
+rcm ensure                 # Install missing dependencies
+🏗️ Architecture Highlights
+Smart Package Detection:
+
+Automatically detects package manager based on name patterns
+Falls back to workspace context (Cargo.toml, package.json, etc.)
+Interactive selection when ambiguous
+
+LET Command Flexibility:
+
+Conditional execution based on file existence, platform, environment
+Parallel execution with configurable job counts
+Environment-specific configurations
+Complex dependency chains
+
+Enterprise Features:
+
+Configuration inheritance and overrides
+Audit trails and compliance reporting
+Workspace snapshots and rollback
+Health scoring and recommendations
+
+This implementation transforms RCM from a simple package manager into a comprehensive polyglot development platform that can handle everything from FFmpeg media processing to complex multi-language CI/CD pipelines, making it ideal for modern development teams working across multiple technology stacks.
+The system is designed with production deployment in mind, featuring robust error handling, comprehensive logging, security-first design, and enterprise-grade configuration management.RetryClaude can make mistakes. Please double-check responses.Continue Sonnet 4
