alter published stored proc in sql server

Hi,

  Have published a database and many subscribers are connected to it. Now I want to alter one of the stored procedure.  I dont want to re-publish the db again. I read in some forum that article for that stored procedure should be deleted and alter the stored proc and recreate the article again.  I dont know how to do it.  Any anyone tell me how can I do this?

  Thanks in advance,

Pavan
