/* These defines are used by setup to modify the user and company name which
   the about box will display.  The location of the user and company name
   are determined by looking for a search tag in the string resource table
   just before the user and company name.  This is why it is very important
   that the following 3 IDS's always be consecutive and within the same
   resource segment.  The same resource segment can be guaranteed by ensuring
   that the IDS's all be within a 16-aligned page (i.e. (n*16) to (n*16 + 15).
