I can think of at least two reasons for breaking up one's package
files. Of course, there are several reasons to not do so as well.
1)
The package needs to use code that is generated from a calculation
that would be prohibitive to run at package load time.
2)
The package is being developed by multiple people using a revision
control system that would make conflicts more likely if there were not
several files.
