Task:

You must create a parser that can parse snippets of a programming language. The language does not need to be complex, but it must include the following syntactical elements:

• Ability to assign and read variables (could be as simple as a-z being premade variables)
• If statements (elseif and else are not required)
• Loops (counting to an arbitrary number, user access to counter is not required)
• Simple math with variables (addition, subtraction, multiplication, division, greater/less than, equals)
• Print statements

Rules:

• You may not copy the syntax of another popular language.
• You need to write your own parser, not modification of another parser.
• You can write your parser in any language.
• Write a 99-bottles-of-beer example program in your language (see here)
• This is a popularity-contest, so the most upvoted answer wins.
