## Grammar Syntax

### Example

    $FOO -> /foo  
    $FOO -> /foo$FOO  
    $FOO -> $BAR  
    $BAR -> /bar  
    $BAR -> $BAR  


### Nonterminals

A Nonterminal starts with a leading `$`. The nonterminal `FOO` would be written as:

    $FOO


### Terminals

A Terminals starts with a leading `/`. The terminal `bar` would be written as:

    /bar

Note that `/ab` differs from `/a/b`. The string `/ab` resolves to the terminal `ab`,
whereas `/a/b` resolves to the terminals `a` and `b`
