Ostrich is an esoteric programming language, designed for code golf. Ostrich programs attempt to be as short as possible, while also being readable for those who know the language.
Ostrich is a stack-based language, which means most instructions act upon the stack. The initial stack is empty.
A list of instructions and what they do can be found in the doc directory.
The name "Ostrich" comes from golf, in which it means a score of 5 under par (which has never been achieved).
