-/**
- * @class ACE_Svc_Conf_Lexer_Guard
- *
- * @brief "Guard" that ensures lexer buffer stack manipulation is
- * exception-safe.
- *
- * Buffers are allocated and deallocated when scanning a file or a
- * string. This class utilizes the "guard" idiom to perform stack
- * pushing and popping before and after parsing/scanning.
- * @par
- * The underlying stack allows nested scans to occur. For example,
- * while scanning a `svc.conf' file, a Service Object's init() method
- * could invoke a Service Configurator directive, which would require
- * "moving" the current lexer state out of the way (pushing it onto
- * the stack implementation).
