Where to declare S4 classes?

OK. Looks like I have got it... going through the source code of sp,
classes are declared as usual functions in *.R files. With the current
example, suppose I must write two files of names "class-Prior.R" and
Suppose the alphabetical order of each file name may be important
somehow, since "SamplePrior" cannot be defined without a prior
definition of "Prior"
Can anybody confirm?
If so, I can go on with validity checking functions...
