+# Make Variables Constexpr Script
+
+This script converts `auto` variable declarations for `$break`, `$continue`, and `any` variables to `static constexpr` declarations in C++ code.
+
+## Purpose
+
+The script addresses issue #23 by automatically converting the following patterns:
+
+- `auto $break = Constants.Break;` → `static constexpr auto $break = Constants.Break;`
+- `auto $continue = Constants.Continue;` → `static constexpr auto $continue = Constants.Continue;`
+- `auto any = Constants.Any;` → `static constexpr auto any = Constants.Any;`
+- `auto $break {Constants.Break};` → `static constexpr auto $break {Constants.Break};`
+- `auto $continue {Constants.Continue};` → `static constexpr auto $continue {Constants.Continue};`
+- `auto any {Constants.Any};` → `static constexpr auto any {Constants.Any};`
+
+## Usage
+
+```bash
+# Process current directory
+./make_constexpr.sh
+
+# Process specific directory
+./make_constexpr.sh /path/to/cpp/project
+
+# Show help
+./make_constexpr.sh --help
+```
+
+## What it does
+
+1. Searches for C++ files (.h, .hpp, .cpp, .cc) in the specified directory
+2. Applies regex transformations to convert auto declarations to constexpr
+3. Only modifies lines that exactly match the expected patterns
+4. Preserves indentation and formatting
+5. Reports which files were modified
+
+## Safety
+
+- Only converts specific patterns that match Constants.Break, Constants.Continue, and Constants.Any
+- Does not modify other auto variable declarations
+- Preserves original file formatting and indentation
+- Shows clear output indicating which files were changed
+
+## Example
+
+Before:
+```cpp
+void someMethod() {
+    auto $break = Constants.Break;
+    auto $continue = Constants.Continue;
+    auto any = Constants.Any;
+}
+```
+
+After:
+```cpp
+void someMethod() {
+    static constexpr auto $break = Constants.Break;
+    static constexpr auto $continue = Constants.Continue;
+    static constexpr auto any = Constants.Any;
+}
+```
