/*::: FUNCTIONAL OVERVIEW ::::::::::

--- revision history ----
9/6/02 Version 1.2.3 Paul Ryan
+ added eus_CursorAdvance()
+ enhanced eus_ReplaceRtfSpanText() so it outputs rich-text span marking 
  replacement
+ improved reliability of ef_CursorToAttachmentHotspot()
+ improved eus_WriteEndHotspotRecord() causing rename to eus_InsertHotspotEnd()

5/30/00 Version 1.2.1 Paul Ryan
+ extended to allow construction of formula action-hotspots

3/20/00 Version 1.2 Paul Ryan
+ improvement, R5-enablement of eus_SubformTop(), associated signature change
+ adjustments made in support of making the PGP Plug-In compatible with the 
  Notes R5 mail template
+ imporvement to span-alignment output of ef_CursorToAttachmentHotspot()
+ bug fix to eus_AppendAttachmentHotspot()
