+# sqlcw - SQL Code Wrapper
+**A lightweight preprocessor for embedding SQL code in host programming languages**
+<br clear="left"/>
+
+sqlcw wraps SQL statements with configurable prefix and suffix strings, making it easy to embed SQL in C++, Python, or other languages. For example, wrapping with prefix `execute(` and suffix `) by cnxn;` transforms standalone SQL into ready-to-use function calls.
+
+The tool is SQL syntax-aware and correctly handles quoted strings, identifiers, and comments. Additional options allow you to strip or convert comments and simplify whitespace.
+
+## Usage
+sqlcw is invoked from the command line. Run with `sqlcw --help` to see all available program options:
