    Walrus is an object-oriented templating system inspired by and similar
    to the Cheetah Python-powered template engine. It includes a Parser
    Expression Grammar (PEG) parser generator capable of generating an
    integrated lexer, "packrat" parser, and Abstract Syntax Tree (AST)
    builder.
