 This library provides some functions that convert string cases between camelCase, COBOL-CASE, kebab-case, MACRO_CASE, PascalCase, snake_case and Train-Case.
+And this library also provides a trait `Caser` which has some methods to convert string cases.
 
 Basically, these functions targets the upper and lower cases of only ASCII alphabets for capitalization, and all characters except ASCII alphabets and ASCII numbers are eliminated as word separators.
