+* Input/Output interface for Lua programs
+* LuaSocket toolkit
+*
+* Line patterns require buffering. Reading one character at a time involves
+* too many system calls and is very slow. This module implements the
+* LuaSocket interface for input/output on connected objects, as seen by 
+* Lua programs. 
+*
+* Input is buffered. Output is *not* buffered because there was no simple
+* way of making sure the buffered output data would ever be sent.
+*
+* The module is built on top of the I/O abstraction defined in io.h and the
+* timeout management is done with the timeout.h interface.
