+	/// Summary description for RefList.
+	/// 
+	/// The RefList class creates, reads, writes, and deletes a file
+	/// of the 'input' name to hold procedure numbers/sequence numbers that
+	/// represent dependencies that need to be addressed (i.e. removed) by
+	/// the user in the editor. This is either for resolving approve selected
+	/// conflicts or deleting a procedure with transitions. (actual current use is
+	/// for approve selected conflicts). 
+	/// The contents of this file is read in and listed via the TranRefsDlg in vfw
+	/// for now, i.e. as long as vfw is the editor.
+	/// The 'input' file is created in the user's Temp directory when in multi-user 
+	/// mode or in the procedure directory when a lock is set or when in single user \
+	/// mode.
+	/// </summary>
