<!-- BIRD Programmer's Guide: Sysdeps (c) 2000 Martin Mares <email@example.com>--><chapt>System dependent parts<sect>Introduction<p>We've tried to make BIRD as portable as possible, but unfortunatelycommunication with the network stack differs from one OS to another,so we need at least some OS specific code.

for all Unices).<tagp/Logging module/ manages the system logs. [per OS family]<tagp/IO module/ gives an implementation of sockets, timers and theglobal event queue. [per OS family]<tagp/KRT module/ implements the Kernel and Device protocols.
