http update ports tree using subversion

OK, I agree and have decided on using this directory:

/opt/local/var/db/dports/sources/http.svn.macports.org_dports

for the subversion working copy, as this will avoid possible conflict  
with current MacPorts.

Now I have a question about manual selfupdate, how do I manually  
update MacPorts? From reading the GettingStarted-MacPorts-Trac wiki  
page and snooping around darwinports tcl code, it looks like I can  
run subversion on

http://svn.macports.org/repository/macports/trunk/base

and write the working copy to

/opt/local/var/db/dports/sources/http.svn.macports.org_base

Then compare my working copy base/config/dp_version to MP's dpupdate1/ 
base/config/dp_version and if newer, then
./configure
make
make install

Looks like a lot of repetitive work. I'm tempted to hack the  
selfupdate routine in my working copy of base/src/darwinports1.0/ 
darwinports.tcl.
