-# Dose - Zig Port
-
-This is a Zig port of the original Rust-based DOS command shell implementation.
-
-## Dependency Replacements
-
-The original Rust version used several external crates that have been replaced with Zig standard library functionality:
-
-### Rust → Zig Replacements
-- **`rustyline`** (command-line editing) → Simple `stdin.readUntilDelimiterOrEofAlloc()` 
-- **`crossterm`** (terminal manipulation) → ANSI escape sequences for screen clearing
-- **`prettytable-rs`** (table formatting) → Custom formatting with `print()`
-- **`eyre`/`color-eyre`** (error handling) → Zig's built-in error handling
-- **`thiserror`** (error derive macros) → Zig error unions
-- **`regex`** (regular expressions) → Not needed in current implementation
-
-### Key Architectural Changes
-
-1. **Error Handling**: Replaced Rust's `Result<T, E>` with Zig's error unions (`!T`)
-2. **Memory Management**: Manual allocation/deallocation using Zig's allocators instead of Rust's ownership system
-3. **String Handling**: Explicit memory management for strings vs Rust's `String`/`&str`
-4. **Concurrency**: Removed complex threading from original Rust version for simplicity
-5. **Command Line Editing**: Simplified to basic line reading (no history or editing features)
-
-### Missing Features (compared to Rust version)
-- Command-line history and editing (rustyline features)
-- Colored error output
-- Advanced terminal manipulation
-- Complex pipe/redirection handling
-- Multi-threaded command execution
-
-## Build Instructions
-
-```bash
-# Build and run in debug mode
-zig build run
-
-# Build optimized release version  
-zig build -Doptimize=ReleaseFast
-
-# Run tests
-zig build test
-```
-
-## Implementation Notes
-
-The Zig version focuses on core DOS command functionality while maintaining the same architectural patterns as the Rust original. The enum-based command system has been preserved using Zig's union types.
-
-Key DOS commands implemented:
-- `ECHO` (with ON/OFF variants)
-- `CLS` (clear screen)  
-- `EXIT` (exit shell)
-- `VER` (version info)
-- `DATE` and `TIME` (system date/time)
-- `DIR` (directory listing)
-
-The implementation uses Zig's standard library exclusively, avoiding external dependencies for better portability and simplicity.
