+# cflat (c♭)
+
+**Make your C++ project fall flat.**
+
+## What is this?
+
+`cflat` takes your complex directory structure and exports it into a single text file. It merges your entire C/C++ project into one massive stream of code.
+
+**Note:** It does not actually delete your folders. It just ignores them in the output. Your architecture is safe.
+
+## Why?
+
+Civilized people keep files separate. You, apparently, need them together.
+
+* **AI Fodder:** Feed your entire codebase to an LLM so it can hallucinate a fix for that segfault you've been ignoring.
+* **Code Reviews:** Send a single 50,000-line file to your reviewer. Assert dominance.
+* **Grepping:** Search for a string across the project instantly because you still haven't memorized how to use `grep -r`.
+* **Spite:** Annoy your lead architect by rendering their carefully crafted folder structure irrelevant.
+
+## Features
+
+* **Recursive:** It hunts down source files in every nested folder. Deep sub-directories are no longer safe places to hide bad code.
+* **Fake Elegance:** It runs `clang-format` (if installed) so your spaghetti code at least *looks* professional in the export.
+* **Hygiene:** It ignores `obj`, `bin`, `.git`, and other binary garbage that nobody wants to read.
+* **Self-Preservation:** It automatically adds itself and the output file to `.gitignore`. This prevents you from accidentally committing a 12MB text file.
+* **Flexible:** Run it on the current folder, a target folder, or exclude specific shameful directories.
+
+## Installation
+
+Trusting random scripts from the internet is a key part of the developer experience.
+
+```bash
+curl -O https://git.alidavid.hu/david/cflat/raw/branch/main/cflat
+```
+
+Make it executable:
+
+```bash
+chmod +x cflat
+```
+
+## Usage
+
+**Default Behavior:**
+Run this in your project root to flatten everything.
+
+```bash
+./cflat
+```
+
+**Target a specific folder:**
+
+```bash
+./cflat ../my-other-project/
+```
+
+**The "Denial" option (Exclusions):**
+Exclude folders you don't want the world (or the AI) to see.
+
+```bash
+./cflat -e build -e node_modules -e "legacy_code"
+```
+
+### ⚠️ Wildcards (Important)
+
+Your shell expands `*` before the script sees it. If you don't use quotes, the script will break.
+
+```bash
+# Good:
+./cflat -e "*.tmp"
+
+# Bad (The shell expands this and confuses the script):
+./cflat -e *.tmp
+```
+
+**Need help?**
+
+```bash
+./cflat -?
+```
+
+## Output
+
+The script generates a file named `cflat-export-YYYY-MM-DD.txt`. It contains:
+
+1. **Project Stats:** How many lines of code you are dealing with.
+2. **The Tree:** A visual map of the directory structure.
+3. **The Cast:** A list of all classes and structs found.
+4. **The Blob:** The full content of every source file, stitched together.
+
+## Requirements
+
+* **OS:** Linux or macOS. (Windows users: please use WSL).
+* **Shell:** Bash.
+* **Optional:**
+  * `tree`: For structure visualization.
+  * `clang-format`: For code cleaning.
