 * @brief Internal things just needed for building the library, but

 * not to be installed.

 * @mainpage

 * Liblognorm is an easy to use and fast samples-based log normalization

 * library.

 *

 * It can be passed a stream of arbitrary log messages, one at a time, and for

 * each message it will output well-defined name-value pairs and a set of

 * tags describing the message.

 *

 * For further details, see it's initial announcement available at

 *    http://blog.gerhards.net/2010/10/introducing-liblognorm.html

 *

 * The public interface of this library is describe in liblognorm.h.

 *

 * Liblognorm fully supports Unicode. Like most Linux tools, it operates

 * on UTF-8 natively, called "passive mode". This was decided because we

 * so can keep the size of data structures small while still supporting

 * all of the world's languages (actually more than when we did UCS-2).

 *

 * At the  technical level, we can handle UTF-8 multibyte sequences transparently.

 * Liblognorm needs to look at a few US-ASCII characters to do the

 * sample base parsing (things to indicate fields), so this is no

 * issue. Inside the parse tree, a multibyte sequence can simple be processed

 * as if it were a sequence of different characters that make up a their

 * own symbol each. In fact, this even allows for somewhat greater parsing

 * speed.
