Help with svn:externals

Hi,

After reading the svn Handbook section on the svn:externals property
tag, I find that I'm still a little confused on what it is good for
and how it is used.

I recently read an article in Linux Journal about someone who kept
their entire homedir under CVS control and used CVS modules to make
it a bit more manageable.

svn:externals *seems* to be the analgous to CVS modules. However,
I know very little about CVS at that level, having simply used it to
check out from repos managed by others. As a result, since I don't
even understand that, I find it difficult to grasp the svn:externals
stuff as well.

Could someone be so kind as to explain how/why you would use
svn:externals? If other docs exist explaining it differently
than the Handbook, pointers to those would be greatly appreciated as
well (would it be worth reading the modules section at red bean?).

Thanks,
