/*! \file isc/lex.h
 * \brief The "lex" module provides a lightweight tokenizer.  It can operate
 * on files or buffers, and can handle "include".  It is designed for
 * parsing of DNS master files and the BIND configuration file, but
 * should be general enough to tokenize other things, e.g. HTTP.
 *
 * \li MP:
 *	No synchronization is provided.  Clients must ensure exclusive
 *	access.
 *
 * \li Reliability:
 *	No anticipated impact.

 *	TBS
 *
 * \li Security:
 *	No anticipated impact.
 *
 * \li Standards:
 * 	None.
