1) Download the latest version of the field system software
	use http://www.metsahovi.fi/fs
	or ftp://atri.gsfc.nasa.gov
	
	Login with proper user credentials
	the latest stable version is in the dist directory

2) Installation
	Log into mrt-vlbi as user prog
	cd /
	tar xzvf <fs-download-file>

	This will unpack the code into /usr2/fs-<version> e.g. /usr2/fs-9.11.6

	cd /usr2/fs-<version>
	make
	(This should build the field system without throwing errors)

3) Activation of new version
	as user prog:
	cd /usr2
	rm fs
	rm control
	cp -r control-<previousVersion> control-<newVersion>
		e.g. cp -r control-9.10.5 control-9.11.6
	ln -s fs-<newVersion> fs
	ln -s control-<newVersion> control

4) Testing new version
	as user oper:
	fs
	
	This should start the fs without any errors. 
	Typical errors thrown are related to new required parameters in the 		equip.ctl or other control files. In this case you can find templates of 		the new syntax of these files under /usr2/fs/st.default/control. 

	Also the proper functionality of the station code should be verified.
