Preferred way of adding truetype fonts in debian?

[Olle Eriksson <pt00oer@student.bth.se>]

I'm seeing tons of information regarding this issue on the net and it's 
difficult to tell what is current and what is deprecated information and 
what is best to do on a Debian system. Could you help me out?

I have a windows partition available with the appropriate ttf files but I 
am not sure what the preferred debian way of installing them is. I have 
defoma installed, as well as msttcorefonts. I just now saw that the KDE 
tool KFontView has an option to install fonts. Will that make fonts 
available only to KDE? How should I do?

Thanks
