-# Generic Automatic Version Increment System for Any Repository
-
-Here's a generalized implementation guide for adding automatic versioning to any project:
-
-## Core Concept
-**Automatic patch version increment with each build** - Every build automatically increments the patch version: v0.1.0 → v0.1.1 → v0.1.2, etc.
-
-## Implementation Steps
-
-### 1. Add Version Increment Function to Build Script
-Add this function to your build script (bash example):
-
-```bash
-# Function to automatically increment version
-increment_version() {
-    echo "[INFO] Incrementing version..."
-    
-    # Check if we're in a git repository
-    if ! git rev-parse --git-dir > /dev/null 2>&1; then
-        echo "[WARNING] Not in a git repository - skipping version increment"
-        return 0
-    fi
-    
-    # Get the highest version tag (not chronologically latest)
-    LATEST_TAG=$(git tag -l 'v*.*.*' | sort -V | tail -n 1 || echo "v0.1.0")
-    if [[ -z "$LATEST_TAG" ]]; then
-        LATEST_TAG="v0.1.0"
-    fi
-    
-    # Extract version components (remove 'v' prefix)
-    VERSION=${LATEST_TAG#v}
-    
-    # Parse major.minor.patch using regex
-    if [[ $VERSION =~ ^([0-9]+)\.([0-9]+)\.([0-9]+)$ ]]; then
-        MAJOR=${BASH_REMATCH[1]}
-        MINOR=${BASH_REMATCH[2]}
-        PATCH=${BASH_REMATCH[3]}
-    else
-        echo "[ERROR] Invalid version format in tag: $LATEST_TAG"
-        echo "[ERROR] Expected format: v0.1.0"
-        return 1
-    fi
-    
-    # Increment patch version
-    NEW_PATCH=$((PATCH + 1))
-    NEW_VERSION="v${MAJOR}.${MINOR}.${NEW_PATCH}"
-    
-    echo "[INFO] Current version: $LATEST_TAG"
-    echo "[INFO] New version: $NEW_VERSION"
-    
-    # Create new git tag
-    if git tag "$NEW_VERSION" 2>/dev/null; then
-        echo "[SUCCESS] Created new version tag: $NEW_VERSION"
-    else
-        echo "[WARNING] Tag $NEW_VERSION already exists - using existing version"
-        NEW_VERSION=$LATEST_TAG
-    fi
-    
-    # Update VERSION file for compatibility
-    echo "${NEW_VERSION#v}" > VERSION
-    echo "[SUCCESS] Updated VERSION file to ${NEW_VERSION#v}"
-}
-```
-
-### 2. Generate Version Header Files (For C/C++ Projects)
-Add this to the increment_version function:
-
-```bash
-# Generate version.h header file (adjust path as needed)
-cat > src/version.h << EOF
-/*
- * Auto-Generated Version Header
- * DO NOT EDIT THIS FILE MANUALLY - Generated by build script
- */
-
-#ifndef VERSION_H
-#define VERSION_H
-
-#define VERSION_MAJOR ${MAJOR}
-#define VERSION_MINOR ${MINOR}
-#define VERSION_PATCH ${NEW_PATCH}
-#define VERSION_STRING "${MAJOR}.${MINOR}.${NEW_PATCH}"
-#define VERSION_TAG "${NEW_VERSION}"
-
-/* Build information */
-#define BUILD_DATE "$(date +%Y-%m-%d)"
-#define BUILD_TIME "$(date +%H:%M:%S)"
-#define BUILD_TIMESTAMP "$(date '+%Y-%m-%d %H:%M:%S')"
-
-/* Git information */
-#define GIT_HASH "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
-#define GIT_BRANCH "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
-
-/* Display versions */
-#define VERSION_DISPLAY "${NEW_VERSION}"
-#define VERSION_FULL_DISPLAY "${NEW_VERSION} ($(date '+%Y-%m-%d %H:%M:%S'), $(git rev-parse --short HEAD 2>/dev/null || echo 'unknown'))"
-
-/* Version API functions */
-const char* get_version(void);
-const char* get_version_full(void);
-const char* get_build_info(void);
-
-#endif /* VERSION_H */
-EOF
-
-# Generate version.c implementation file
-cat > src/version.c << EOF
-/*
- * Auto-Generated Version Implementation
- * DO NOT EDIT THIS FILE MANUALLY - Generated by build script
- */
-
-#include "version.h"
-
-const char* get_version(void) {
-    return VERSION_TAG;
-}
-
-const char* get_version_full(void) {
-    return VERSION_FULL_DISPLAY;
-}
-
-const char* get_build_info(void) {
-    return "Built on " BUILD_DATE " at " BUILD_TIME " from commit " GIT_HASH " on branch " GIT_BRANCH;
-}
-EOF
-```
-
-### 3. Generate Version File for Other Languages
-
-**Python (`src/__version__.py`):**
-```bash
-cat > src/__version__.py << EOF
-"""Auto-generated version file"""
-__version__ = "${MAJOR}.${MINOR}.${NEW_PATCH}"
-__version_tag__ = "${NEW_VERSION}"
-__build_date__ = "$(date +%Y-%m-%d)"
-__build_time__ = "$(date +%H:%M:%S)"
-__git_hash__ = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
-__git_branch__ = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
-EOF
-```
-
-**JavaScript/Node.js (update `package.json`):**
-```bash
-# Update package.json version field
-if [ -f package.json ]; then
-    sed -i "s/\"version\": \".*\"/\"version\": \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" package.json
-fi
-```
-
-**Rust (update `Cargo.toml`):**
-```bash
-if [ -f Cargo.toml ]; then
-    sed -i "s/^version = \".*\"/version = \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" Cargo.toml
-fi
-```
-
-**Go (generate `version.go`):**
-```bash
-cat > version.go << EOF
-// Auto-generated version file
-package main
-
-const (
-    VersionMajor = ${MAJOR}
-    VersionMinor = ${MINOR}
-    VersionPatch = ${NEW_PATCH}
-    VersionString = "${MAJOR}.${MINOR}.${NEW_PATCH}"
-    VersionTag = "${NEW_VERSION}"
-    BuildDate = "$(date +%Y-%m-%d)"
-    BuildTime = "$(date +%H:%M:%S)"
-    GitHash = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
-    GitBranch = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
-)
-EOF
-```
-
-**Java (generate `Version.java`):**
-```bash
-cat > src/main/java/Version.java << EOF
-// Auto-generated version class
-public class Version {
-    public static final int VERSION_MAJOR = ${MAJOR};
-    public static final int VERSION_MINOR = ${MINOR};
-    public static final int VERSION_PATCH = ${NEW_PATCH};
-    public static final String VERSION_STRING = "${MAJOR}.${MINOR}.${NEW_PATCH}";
-    public static final String VERSION_TAG = "${NEW_VERSION}";
-    public static final String BUILD_DATE = "$(date +%Y-%m-%d)";
-    public static final String BUILD_TIME = "$(date +%H:%M:%S)";
-    public static final String GIT_HASH = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')";
-    public static final String GIT_BRANCH = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')";
-}
-EOF
-```
-
-### 4. Integrate into Build Targets
-Call `increment_version` before your main build commands:
-
-```bash
-build_library() {
-    increment_version
-    echo "[INFO] Building library..."
-    # Your actual build commands here
-    make clean && make
-}
-
-build_release() {
-    increment_version
-    echo "[INFO] Building release..."
-    # Your release build commands
-}
-
-build_package() {
-    increment_version
-    echo "[INFO] Building package..."
-    # Your packaging commands
-}
-```
-
-### 5. Update .gitignore
-Add generated version files to `.gitignore`:
-
-```gitignore
-# Auto-generated version files
-src/version.h
-src/version.c
-src/__version__.py
-version.go
-src/main/java/Version.java
-VERSION
-```
-
-### 6. Update Build System Files
-
-**For Makefile projects:**
-```makefile
-# Add version.c to your source files
-SOURCES = main.c utils.c version.c
-```
-
-**For CMake projects:**
-```cmake
-# Add version files to your target
-target_sources(your_target PRIVATE src/version.c)
-```
-
-**For Node.js projects:**
-```json
-{
-  "scripts": {
-    "build": "node build.js && increment_version",
-    "version": "node -e \"console.log(require('./package.json').version)\""
-  }
-}
-```
-
-### 7. Create Initial Version Tag
-```bash
-# Start with initial version
-git tag v0.1.0
-```
-
-## Usage Pattern
-```bash
-./build.sh          # v0.1.0 → v0.1.1
-./build.sh release  # v0.1.1 → v0.1.2
-./build.sh package  # v0.1.2 → v0.1.3
-```
-
-## Manual Version Control
-
-### Major/Minor Version Bumps
-```bash
-# For feature releases (minor bump)
-git tag v0.2.0  # Next build: v0.2.1
-
-# For breaking changes (major bump)
-git tag v1.0.0  # Next build: v1.0.1
-```
-
-### Version Reset
-```bash
-# Delete incorrect tags (if needed)
-git tag -d v0.2.1
-git push origin --delete v0.2.1  # If pushed to remote
-
-# Create correct base version
-git tag v0.2.0
-
-# Next build will create v0.2.1
-```
-
-## Example Build Script Template
-```bash
-#!/bin/bash
-set -e
-
-# Colors for output
-RED='\033[0;31m'
-GREEN='\033[0;32m'
-YELLOW='\033[1;33m'
-BLUE='\033[0;34m'
-NC='\033[0m'
-
-print_status() { echo -e "${BLUE}[INFO]${NC} $1"; }
-print_success() { echo -e "${GREEN}[SUCCESS]${NC} $1"; }
-print_warning() { echo -e "${YELLOW}[WARNING]${NC} $1"; }
-print_error() { echo -e "${RED}[ERROR]${NC} $1"; }
-
-# Insert increment_version function here
-
-case "${1:-build}" in
-    build)
-        increment_version
-        print_status "Building project..."
-        # Your build commands
-        ;;
-    clean)
-        print_status "Cleaning build artifacts..."
-        # Your clean commands
-        ;;
-    test)
-        print_status "Running tests..."
-        # Your test commands (no version increment)
-        ;;
-    release)
-        increment_version
-        print_status "Building release..."
-        # Your release commands
-        ;;
-    *)
-        echo "Usage: $0 {build|clean|test|release}"
-        exit 1
-        ;;
-esac
-```
-
-## Benefits
-1. **Zero maintenance** - No manual version editing
-2. **Build traceability** - Every build has unique version + metadata
-3. **Git integration** - Automatic version tags
-4. **Language agnostic** - Adapt generation for any language
-5. **CI/CD friendly** - Works in automated environments
-6. **Rollback friendly** - Easy to revert to previous versions
-
-## Troubleshooting
-
-### Version Not Incrementing
-- Ensure you're in a git repository
-- Check that git tags exist: `git tag --list`
-- Verify tag format matches `v*.*.*` pattern
-
-### Tag Already Exists
-If a tag already exists, the build continues with existing version:
-```
-[WARNING] Tag v0.2.1 already exists - using existing version
-```
-
-### Missing Git Information
-If git is unavailable, version files show "unknown" for git hash and branch.

 ### Generated Files
-The build system automatically generates:
-- `src/version.h` - Version constants and macros
-- `src/version.c` - Version API functions  
-- `VERSION` - Plain text version number
+The build system automatically manages Git versioning by incrementing tags.
 
 These files are excluded from git (.gitignore) and regenerated on each build.
