Proper way to update ports with svn

[Andre Goree]

I seem to have to run 'make index' in /usr/ports after I've run 'svn up
/usr/ports' in order to see which ports need to be updated using
'portversion'.  This doesn't seem correct...and if so portsnap would
seem like a much better tool.  Perhaps I should be running 'make
fetchindex' instead?  I'm sure I've read about the correct way to do so,
but it doesn't appear to be here:

Thanks in advance for any advice.
