9 Ruby is an interpreted object-oriented programming language often
10 used for web development. It also offers many scripting features
11 to process plain text and serialized files, or manage system tasks.
12 It is simple, straightforward, and extensible.
17 * **Normal** Object-oriented Features (e.g. class, method calls)
18 * **Advanced** Object-oriented Features (e.g. mix-in, singleton-method)
19 * Operator Overloading
21 * Iterators and Closures
23 * Dynamic Loading of Object Files (on some architectures)
24 * Highly Portable (works on many Unix-like/POSIX compatible platforms as
25 well as Windows, macOS, etc.) cf.
