-**Content Cleaner for tst Files**
+# VectorCAST Test File Content Cleaner
 
-This Python script is designed to remove specific patterns from C files, particularly content between TEST.IMPORT_FAILURES: and TEST.END_IMPORT_FAILURES: without affecting the surrounding lines.

-**How It Works**
+A robust Python utility designed to clean VectorCAST C test files by removing import failure blocks while preserving file structure and integrity. This tool is essential for VectorCAST test environment maintenance and automated test processing workflows.
 
-The script uses regular expressions to identify and remove content blocks that start with TEST.IMPORT_FAILURES: and end with TEST.END_IMPORT_FAILURES:. The surrounding whitespace is preserved to ensure the integrity of the original file's structure.
+## 🚀 Features
 
-**Usage**
+- **Smart Content Removal**: Precisely removes `TEST.IMPORT_FAILURES:` to `TEST.END_IMPORT_FAILURES:` blocks
+- **File Integrity**: Preserves original file structure and formatting
+- **Backup Protection**: Automatic backup creation before file modification
+- **Batch Processing**: Support for cleaning multiple files simultaneously
+- **Error Handling**: Comprehensive error handling with detailed logging
+- **CLI Interface**: Both interactive and command-line modes
+- **Unicode Support**: Handles various text encodings gracefully
 
-Ensure you have Python installed on your machine.
+## 🛠️ Installation
 
-Run the script using the command:
+### Prerequisites
+- Python 3.7 or higher
+- Standard Python libraries (no additional dependencies required)
 
+### Setup
+```bash
+# Clone the repository
+git clone https://github.com/yourusername/vectorcast-content-cleaner.git
+cd vectorcast-content-cleaner
+
+# Make the script executable (optional)
+chmod +x content_cleaner.py
+```
+
+## 📖 Usage
+
+### Interactive Mode
+```bash
 python content_cleaner.py
+```
+
+### Command Line Mode
+```bash
+# Clean a single file
+python content_cleaner.py test_file.c
+
+# Clean multiple files
+python content_cleaner.py file1.c file2.c file3.c
+
+# Clean without creating backups
+python content_cleaner.py test_file.c --no-backup
+
+# Enable verbose logging
+python content_cleaner.py test_file.c --verbose
+```
+
+### Command Line Options
+```
+positional arguments:
+  files              File(s) to clean. If not provided, will prompt for input
+
+optional arguments:
+  -h, --help         Show help message and exit
+  --no-backup        Don't create backup files
+  --verbose, -v      Enable verbose logging
+  --version          Show program's version number and exit
+```
+
+## 🔧 How It Works
+
+The cleaner uses advanced regular expressions to identify and remove content blocks that match the VectorCAST import failure pattern:
+
+```c
+// This content will be removed:
+TEST.IMPORT_FAILURES:
+    Any content here including
+    multiple lines and special characters
+TEST.END_IMPORT_FAILURES:
+```
+
+### Algorithm Details
+1. **Pattern Recognition**: Uses regex with multiline and dotall flags for accurate matching
+2. **Content Preservation**: Maintains surrounding code structure and whitespace
+3. **Cleanup Process**: Removes excessive whitespace that might result from block removal
+4. **Validation**: Checks file permissions and encoding before processing
+
+## 🎯 VectorCAST Integration
+
+### Why This Tool Is Important for VectorCAST
+
+VectorCAST is a comprehensive C/C++ software testing platform used for:
+- **Unit Testing**: Automated test case generation and execution
+- **Integration Testing**: Component-level testing with coverage analysis
+- **Certification**: DO-178B/C, ISO 26262, and other safety-critical standards compliance
+
+#### The Problem This Tool Solves
+
+During VectorCAST test execution, import failure blocks are automatically generated when:
+- Header files cannot be properly parsed
+- Dependencies are missing or misconfigured
+- Compilation issues occur during test environment setup
+
+These blocks accumulate in test files and can cause:
+- **Test Environment Corruption**: Preventing proper test regeneration
+- **Build Failures**: Interfering with subsequent test compilation
+- **Maintenance Issues**: Making test files difficult to manage and version control
+- **CI/CD Pipeline Breaks**: Causing automated testing workflows to fail
+
+#### Business Impact
+
+| Challenge | Impact | Solution with This Tool |
+|-----------|---------|-------------------------|
+| **Manual Cleanup** | Hours of manual editing | **Automated Processing** |
+| **Error-Prone Process** | Risk of removing critical code | **Precise Pattern Matching** |
+| **Team Productivity** | Delayed test cycles | **Batch Processing Capability** |
+| **Quality Assurance** | Inconsistent test environments | **Reliable, Repeatable Cleaning** |
+
+### Use Cases in VectorCAST Workflows
+
+1. **Test Environment Reset**: Clean corrupted test files before regeneration
+2. **CI/CD Integration**: Automated cleanup in build pipelines
+3. **Migration Projects**: Prepare test files when moving between VectorCAST versions
+4. **Maintenance Scripts**: Regular cleanup of test repositories
+5. **Development Workflows**: Quick cleanup during active test development
+
+## 📊 Performance & Reliability
+
+- **Fast Processing**: Optimized regex patterns for quick file processing
+- **Memory Efficient**: Processes files without loading entire content into memory unnecessarily
+- **Error Recovery**: Graceful handling of encoding issues and file permission problems
+- **Backup Safety**: Automatic backup creation prevents data loss
+
+## 🧪 Testing
+
+The project includes comprehensive test coverage:
+
+```bash
+# Run tests
+python -m pytest tests/
+
+# Run with coverage
+python -m pytest tests/ --cov=content_cleaner --cov-report=html
