I don't think this would be as hard to implement as you seem to think it would be.<br>
<br>
As a first try, a really simple s/$oldchecksum/$newchecksum/ would probably work (I'm perhaps not creative enough to think of a use-case where that would false-positive and change something unintended).<br>

It is a python script that drives the port command to determine what (if any) checksums need to be updated for a port, and then uses sed to actually (s/old/new/) update<span></span> it. It runs sed with no backup, so it is best used in an svn version so you can see what it has changed. (Or it could be modified to create a backup file easily enough.)</div><div><br></div><div> - Eric </div>
