Hey, guys
   I'm writing a SAS library used to provide high-qulity SAS macros. I have completed the basic framework of this library. I need to fullfil useful SAS macros based on this framework, then this project could be called a SAS library. Does anyone interest it, please contact me on github, or ask for merge request.
