+/*
+ * ISC Application Support
+ *
+ * Dealing with program termination can be difficult, especially in a
+ * multithreaded program.  The routines in this module help coordinate
+ * the shutdown process.  They are used as follows by the initial (main)
+ * thread of the application:
+ *
+ *		isc_app_start();	Call very early in main(), before
+ *					any other threads have been created.
+ *
+ *		isc_app_run();		This will post any on-run events,
+ *					and then block until application
+ *					shutdown is requested.  A shutdown
+ *					request is made by calling
+ *					isc_app_shutdown(), or by sending
+ *					SIGINT or SIGTERM to the process.
+ *					After isc_app_run() returns, the
+ *					application should shutdown itself.
+ *
+ *		isc_app_finish();	Call very late in main().
+ *
+ * Applications that want to use SIGHUP/isc_app_reload() to trigger reloading
+ * should check the result of isc_app_run() and call the reload routine if
+ * the result is ISC_R_RELOAD.  They should then call isc_app_run() again
+ * to resume waiting for reload or termination.
+ *
+ * Use of this module is not required.  In particular, isc_app_start() is
+ * NOT an ISC library initialization routine.
+ *
+ * MP:
+ *	Clients must ensure that isc_app_start(), isc_app_run(), and
+ *	isc_app_finish() are called at most once.  isc_app_shutdown()
+ *	is safe to use by any thread (provided isc_app_start() has been
+ *	called previously).
+ *
+ * Reliability:
+ *	No anticipated impact.
+ *
+ * Resources:
+ *	None.
+ *
+ * Security:
+ *	No anticipated impact.
+ *
+ * Standards:
+ *	None.

+ * Buffers
+ *
+ * A buffer is a region of memory, together with a set of related subregions.
+ * Buffers are used for parsing and I/O operations.
+ *
+ * The 'used region' and the 'available' region are disjoint, and their
+ * union is the buffer's region.  The used region extends from the beginning
+ * of the buffer region to the last used byte.  The available region
+ * extends from one byte greater than the last used byte to the end of the
+ * buffer's region.  The size of the used region can be changed using various
+ * buffer commands.  Initially, the used region is empty.
+ *
+ * The used region is further subdivided into two disjoint regions: the
+ * 'consumed region' and the 'remaining region'.  The union of these two
+ * regions is the used region.  The consumed region extends from the beginning
+ * of the used region to the byte before the 'current' offset (if any).  The
+ * 'remaining' region the current pointer to the end of the used
+ * region.  The size of the consumed region can be changed using various
+ * buffer commands.  Initially, the consumed region is empty.
+ *
+ * The 'active region' is an (optional) subregion of the remaining region.
+ * It extends from the current offset to an offset in the remaining region
+ * that is selected with isc_buffer_setactive().  Initially, the active region
+ * is empty.  If the current offset advances beyond the chosen offset, the
+ * active region will also be empty.

+ * ISC Message Catalog
+ *
+ * Message catalogs aid internationalization of applications by allowing
+ * messages to be retrieved from locale-specific files instead of
+ * hardwiring them into the application.  This allows translations of
+ * messages appropriate to the locale to be supplied without recompiling
+ * the application.
+ *
+ * Notes:
+ *	It's very important that message catalogs work, even if only the
+ *	default_text can be used.
+ *
+ * MP:
+ *	The caller must ensure appropriate synchronization of
+ *	isc_msgcat_open() and isc_msgcat_close().  isc_msgcat_get()
+ *	ensures appropriate synchronization.
+ *
+ * Reliability:
+ *	No anticipated impact.
+ *
+ * Resources:
+ *	<TBS>
+ *
+ * Security:
+ *	No anticipated impact.
+ *
+ * Standards:
+ *	None.
