+///
+/// This function walks through all the files in the specified `directory_path`,

+/// # Arguments
+///
+/// * `directory_path`: A string slice representing the path of the directory to traverse.
+/// * `pattern`: A string slice containing the regular expression pattern to search for.
+/// * `replacement`: A string slice representing the replacement for each matched pattern.
+///
+/// # Examples
+///
+/// ```rust
+/// // Replace a specific pattern in the file contents in the "./data/" directory.
+/// wolfree_sed_in_place("./data/", r"\bFoo\b", "Bar");
+/// ```
+///
+/// This example replaces all occurrences of the word "Foo" with "Bar" in the files inside the "data" directory.
