iPod how to move a library?

[grooveattack]

hi guys

my sis wants to move her itunes library from her old laptop on to a new one and has asked me to do it.

it is basically find the itunes library file and copy it over or is there an easy way to do it? surly apple know people are going to get new computers and hard rives etc. so they must have something to make this easier.

any help is good, thanks.

EDIT: never mind. you know the HELP tab at the top of most apps is really good!
