## Overview

This is a small terminal MP3 tag reader. The user supplies one MP3 path; the program opens it in binary mode, validates and reports the ID3 header, scans frames, parses supported text and TXXX content, and prints results. The frame loop and dispatch live in main.c; get_size.c supplies size decoding and frame-ID validation, while display_frame.c renders supported frame values. The README documents ID3v2.3 support. The graph is based on the supplied tree and source excerpts.

Main entry points: [`main.c`](https://github.com/kushal6245/mp3-tag-reader/blob/main/main.c) (CLI and frame reader), [`display_frame.c`](https://github.com/kushal6245/mp3-tag-reader/blob/main/display_frame.c) (Frame value display), [`get_size.c`](https://github.com/kushal6245/mp3-tag-reader/blob/main/get_size.c) (Header and frame helpers)
