+# note : 2012.02.05 : stole 3 bytes from 'name' to use for host ID and
+#        related (no DBs were created with more than 17 bytes in the
+#        name).  The hostID points at an entry in the host table (text
+#        file, with name given in SkyTable PHU header).  There is no
+#        safety on this, but it is recoverable (by examining the
+#        directories) if misplaced.
+ 
+#        Note that SkyTables from databases generated in the past may
+#        have garbage characters here.  To ensure catch this
+#        condition, we add a header keyword to SkyTables in which the
+#        hostID has been set; if that is not present, the SkyTable
+#        loading software should init these bytes to 0 (== unassigned).
