title: How to determine where, or if, a variable is used in an SSIS package
body: <p>I've inherited a collection of largely undocumented ssis packages.  The entry point package (ie: the one that forks off in a variety of directions to call other packages) defines a number of variables.  I would like to know how these variables are being used, but there doesn't seem to be an equivalent of "right click/Find All References"</p>
  
  <p>Is there a reliable way to determine where these variables are being used?</p>
