-"""Basic infrastructure for asynchronous socket service clients and servers.
-
-There are only two ways to have a program on a single processor do "more
-than one thing at a time".  Multi-threaded programming is the simplest and
-most popular way to do it, but there is another very different technique,
-that lets you have nearly all the advantages of multi-threading, without
-actually using multiple threads. it's really only practical if your program
-is largely I/O bound. If your program is CPU bound, then pre-emptive
-scheduled threads are probably what you really need. Network servers are
-rarely CPU-bound, however.
-
-If your operating system supports the select() system call in its I/O
-library (and nearly all do), then you can use it to juggle multiple
-communication channels at once; doing other work while your I/O is taking
-place in the "background."  Although this strategy can seem strange and
-complex, especially at first, it is in many ways easier to understand and
-control than multi-threaded programming. The module documented here solves
-many of the difficult problems for you, making the task of building
-sophisticated high-performance network servers and clients a snap.
