+ * Simple if statement processor
+ *
+ * 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.
