* Ability to specify port and address to bind to * By default, binds only to 127.0.0.1 port 13666 * Client commands now return usage when no options given * New driver command: getinfo * Added comments all over the place * Used #defines to further document code * Used #defines to set up compile-time defaults, etc. * Cleaned up client command argument analysis in client_functions.c * Beginning support of syslog * Some bug fixes
