+
+=head1 DESCRIPTION
+
+B<OSSP sa> is a thin abstraction library for the BSD socket interface
+for use in conjunction with TCP and UDP protocols. It provides the
+following key features:
+
+=over 4
+
+=item B<Address Abstraction>
+
+Most of the uglyness in the BSD socket API is the necessarity to have to
+deal with the various address structures (C<struct sockaddr_xx>) which
+exist because of both the different network protocols and addressing
+schemes. B<OSSP sa> fully hides this by providing an abstract and
+opaque address type (C<sa_addr_t>) together with four utility functions
+which allow one to convert from the old C<struct sockaddr> and an URL
+specification (C<{tcp,udp}://<host>[:<port>]>) to the C<sa_addr_t> and
+vice versa.
+
+=item B<I/O Timeouts>
+
+Each function of B<OSSP sa> is aware of a central timeout (set by
+sa_timeout(3)), i.e., all I/O operations return C<SA_ERR_SYS> and
+C<errno> set to C<ETIMEDOUT> if this timeout expired before the
+operation was able to succeed. This allows one to easily program
+less-blocking network services.
+
+=item B<Buffered I/O>
+
+If B<OSSP sa> is used for TCP-based stream I/O, internally all I/O
+operations can be performed through input and output buffers (set
+by sa_buffers(3)) for achieving higher I/O performance by doing I/O
+operations on larger messages.
+
+=item B<Convinience I/O Functions>
+
+If B<OSSP sa> is used for TCP-based stream I/O, for convinience reasons
+line reading (sa_readline(3)) and output formatting (sa_printf(3))
+functions are provided, modelled after STDIO's fgets(3) and fprintf(3).
