+# Test for license generator tools
+
+## The purpose
+The 999.ICU project has many(now, the number is 3) license generator tools and it seems that the number of that will continue to grow. Thus I write this test tool to validate the functionality of the tools.
+
+I hope the newly added tools must add test file and pass it.
+
+## Usage 
+For example, if you would like to add a license generator tool written by `ruby`, you just need to copy the `test_go.rs` file and rename it as `test_ruby.rs`, and replace the parameter in `arg()` of the test function.
