//
//  Namespace AcEdSymbolUtilities contains various AutoCAD-specific
//  utilities for working with symbol names, symbol records, and symbol
//  tables.  The main access to the utility functions is through
//  "acedSymUtil()", which you dereference to call the member
//  functions of AcEdSymbolUtilities::Services.
