- * This module can be used to evaluate string representations of C language
- * if constructs. It accepts the following grammar:
- *
- * EXPRESSION := VALUE
- * | VALUE BINOP EXPRESSION
- * | VALUE '?' EXPRESSION ':' EXPRESSION
- *
- * VALUE := '(' EXPRESSION ')'
- * | '!' VALUE
- * | '-' VALUE
- * | '~' VALUE
- * | 'defined' '(' variable ')'
- * | variable
- * | number
- *
- * BINOP := '*' | '/' | '%'
- * | '+' | '-'
- * | '<<' | '>>'
- * | '<' | '>' | '<=' | '>='
- * | '==' | '!='
- * | '&' | '^' | '|'
- * | '&&' | '||'
- *
- * The normal C order of precedence is supported.
