Command-Line File Synchronization Tool

Write a Python script for a command-line file synchronization tool. The script must accept three command-line arguments: 1. `source_path`: The path to the source directory. 2. `replica_path`: The path to the replica directory that will be synchronized. 3. `log_file_path`: The path to a file where all operations will be logged. Core Functionality: 1. **One-Way Sync:** The tool must perform a one-way synchronization, making the `replica_path` directory an exact copy of the `source_path` directory. - Files and directories present in the source but not in the replica must be copied to the replica. - Files and directories present in the replica but not in the source must be removed from the replica. - Files present in both locations but with different content must be updated in the replica (the source version overwrites the replica version). 2. **Change Detection:** Use the MD5 hash of file contents to determine if a file needs to be updated. Do not rely on modification timestamps. 3. **Logging:** Log all file operations (e.g., "COPY file.txt", "REMOVE old_dir", "UPDATE changed.log") to both the console and the specified log file. Each log entry should be timestamped. 4. **Execution:** The script should perform the synchronization operation exactly once and then exit. It should not run in a loop. Requirements: - Use Python 3. - Use the `argparse` library for command-line argument parsing. - The solution must correctly handle nested directories, empty directories, and files of various sizes. - The script should be a single, self-contained file.
