LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client.
The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents.

This DLL models an nular aspheric
surface as described in:
"Annular surfaces in annular field systems"
By Jose M. Sasian
Opt. eng. 36 (12) P 3401-3401 December 1997
This surface is essentially an odd aspheric surface with an offset in the aspheric terms.
The sag is given by:
Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ...
Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

LGPL The license
his project was built and tested with WinAVR-20060125.
Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!!
To build the code, just install WinAVR and run "make" from the console in echomaster and
echoslave subdirs.
"make program" will program the device if you have a AVRISP attached.
Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock
from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST!
Otherwise you wont get any clock signal to the AVR and then you can t program it or reset
the fuses!
The MC1319x has default clock output of 32kHz so you will have to set your programmer to
a very low frequency (<=32kHz/4) to be able to program it while it is running on that!
