## Overview

CLIProject is a C++ command-line interpreter. A user enters a line through the console reader; the interpreter tokenizes and parses it, builds a registered command or pipeline, resolves input and output, then executes it. The command registry documents file operations, stream filters, utilities, batch execution, and history. The graph includes those documented command branches; unsampled command implementations are represented by their exact tree paths, and their internal wiring is not inferred.

Main entry points: [`CommandMap.cpp`](https://github.com/m4444sa/cliproject/blob/main/CommandMap.cpp) (Command registry), [`Pipeline.cpp`](https://github.com/m4444sa/cliproject/blob/main/Pipeline.cpp) (Pipeline executor), [`Interpreter.cpp`](https://github.com/m4444sa/cliproject/blob/main/Interpreter.cpp) (Interpreter), [`Parser.cpp`](https://github.com/m4444sa/cliproject/blob/main/Parser.cpp) (Parser)
