105 name. Originally, the table contained pointers to the name strings in the first
106 field of each entry. However, that leads to a large number of relocations when
107 a shared library is dynamically loaded. A significant reduction is made by
108 putting all the names into a single, large string and then using offsets in the
109 table itself. Maintenance is more error-prone, but frequent changes to this
110 data are unlikely.

112 July 2008: There is now a script called maint/GenerateUtt.py which can be used
113 to generate this data instead of maintaining it entirely by hand. */
