snowflake parser is not recognized

Hi Folks,

I have cloned https://github.com/sqlparser/gsp_demo_java repository and trying to validate snowflake syntax, but instead of snowflake parser library using default oracle parser. 
Is it snowflake not yet  ? any help would be much appreciated 

 `java demos.checksyntax.checksyntax /d D:\gudusoft.gsqlparser.trial /t snowflake`
