awkdiff is the script from scottl that he got from ken a long time
ago... It no longer lives in his home dir, so give it a new home...
This does simple massaging of p4 output to create a useful diff...
The script p4diffbranch will create a diff that includes new and
deleted files unlike the normal diff2 -b command... So will be useful
for extracting patches from p4... It does take a changeset that will
be used to diff against...
