1.19 + *
1.20 + * It differs from atom tables:
1.21 + * - It supports case insensitive lookup.
1.22 + * - It has minimal footprint by not copying the string table.
1.23 + * - It does no locking.
1.24 + * - It returns zero based indexes and const nsCString& as required by its
1.25 + * callers in the parser.
1.26 + * - It is not an xpcom interface - meant for fast lookup in static tables.
1.27 + *
1.28 + * ***REQUIREMENTS***
1.29 + * - It *requires* that all entries in the table be lowercase only.
1.30 + * - It *requires* that the table of strings be in memory that lives at least
1.31 + * as long as this table object - typically a static string array.
