1.30 + * Simple if statement processor
1.31 + *
1.32 + * This module can be used to evaluate string representations of C language
1.33 + * if constructs. It accepts the following grammar:
1.34 + *
1.35 + * EXPRESSION := VALUE
1.36 + * | VALUE BINOP EXPRESSION
1.37 + * | VALUE '?' EXPRESSION ':' EXPRESSION
1.38 + *
1.39 + * VALUE := '(' EXPRESSION ')'
1.40 + * | '!' VALUE
1.41 + * | '-' VALUE
1.42 + * | '~' VALUE
1.43 + * | 'defined' '(' variable ')'
1.44 + * | variable
1.45 + * | number
1.46 + *
1.47 + * BINOP := '*' | '/' | '%'
1.48 + * | '+' | '-'
1.49 + * | '<<' | '>>'
1.50 + * | '<' | '>' | '<=' | '>='
1.51 + * | '==' | '!='
1.52 + * | '&' | '^' | '|'
1.53 + * | '&&' | '||'
1.54 + *
1.55 + * The normal C order of precedence is supported.
