//////////////////////////////////////////////////////////////////
// "Slurp" (aka "Leech") refers to the ability of an application
// to receive DDE messages to open a document.  For example, the
// user can double-click on a foo.abw document in Windows Explorer
// and (if we're properly registered with the system) it will hand
// the document to us (either to an existing process or launch an
// instance and then hand it to us).
//
// The less-than-polite name for this file reflects that amount of
// pain endured in writing the code -- and the amount of time
// required to find any documentation on the subject (search MSDN
// for: "SAMPLE: How to Use File Associations", Article ID Q1222787,
// August 5, 1996.
//
// It appears that the above cited document is not quite correct
// (or rather is not aging well)...  The examples show setting
// on "HKEY_CLASSES_ROOT\<foo>" to "File_assoc", but this string
// is the value used by WindowsExplorer and the FileOpen dialog
// to describe the document type.
