1. All folders contains both input file and output file of one test.
2. Output files are consists two files: 
	a) Code-listing file which is output of "scanner" of list of original source code. The file name is 
	"sourceCodeFileName" + '0'+ ".txt".
	b) Rule-listing file which is output of "parser" of list of grammar rules used by source code. The file 
	name is "sourceCodeFileName"+'1'+".txt".
3. Scanner errors are output to code-listing file. And syntactical and semantical error are all output to rule-listing
	file.
4. Each test has a certain testing purpose and it is usually written in "sourceCodeFile" in forms of "comment".
5. Syntax error is regarded as serious error and usually will cause parser to stop. My parser doesn't support error-
	recovery functionality.

6. You are welcome to run your own test by following procedure:
	a) Make sure you put both executable file: "CFGReader.exe" and grammar source file: "ruletest.txt" and
	source code input file: "test.txt" all at same folder.
	b) Editing your source code in "test.txt". After saving, run "CFGReader.exe" at command line without any parameter.
	c) If you want to use your own grammar rule source file or other source code file name, following below procedure:
		At command line print "CFGReader.exe YourGrammarRuleFileName YourSourceCodeFileName".
