hi , 

I want write a emacs lisp in the script mode as a shell command (like a man  command) for my personal project . i want use an org file to keep all command
information, like : 

* command_a   :command: 
  some description or params for this command 

* command_b :command: 
  blabala

* some msic information   

then write a help command to show a help for specific command based on tag query , like 

help command_a will display : 

  some description or params for this command 


Thanks ,
