TACO is an object oriented control system originally developed at the European 
Synchrotron Radiation Facility (ESRF) to control accelerators and beamlines and
data acquisition systems. 

At the ESRF (www.esrf.fr) TACO is used to control three accelerators - linear
accelerator , booster synchrotron and storage ring, and over 30 beamlines. 
TACO is being used for instrument control for the new  neutron source FRM-II 
(www.frm2.tum.de) in Garching-Munich. 
TACO has been applied to telescope control at the 26m radio telescope at the 
Hartebeesthoek Radio Astronomy Observatory (www.hartroa.ac.za). 

TACO is very scalable and can be used for simple single device laboratory like
setups with only a few devices or for a big installation comprising thousands 
of devices. TACO is a cheap and simple solution for doing distributed home 
automation. TACO is available free of charge without warranties. 

TACO is object oriented because it treats ALL (physical and logical) control 
points in a control system as objects in a distributed environment. All actions
are implement in classes. New classes can be constructed out of existing 
classes in a hierarchical manner thereby ensuring a high-level of software 
reuse. Classes can be written in C++, in C (using a methodology called Objects 
in C), in Python or in LabView (using G). 

TACO has been designed to be portable and runs on a large number of platforms 
(e.g. Linux, Solaris, BSD, Mac OS X, HP-UX, Win32, OS9). 

If you want to write classes in Python you have to install the Numarray 
package which is available under:
http://www.stsci.edu/resources/software_hardware/numarray 
or
http://numpy.sourceforge.net.

* If a device is defined in different servers the behaviour is unknown.
