 This package contains the server binary as well as its configuration files.
 The default mode of operation is the so called "superclassic", which is a
 multi-threaded server -- each connection starts a separate thread and each
 connection has its own page cache. The two other operation modes -- "classic"
 (separate process/cache for each connection; started from the internet
 super-server inetd or xinetd) and "super" (single-threaded server process with
 shared cache between connections) are also available via configuration options.
