+Idea:
+
+dak update-suite testing testing-kfreebsd
+ -> grab all source & binary packages from testing with a higher version
+ than in testing-kfreebsd (or not in -kfreebsd) and copy them
+ -> limited to architectures in testing-kfreebsd
+ -> obeys policy queues
+ -> copies to build queues
+
+dak update-suite --create-in=ftp-master stable testing
+ -> create suite "testing" based on "stable" in archive "ftp-master"
+
+Additional switches:
+ --skip-policy-queue: skip target suite's policy queue
+ --skip-build-queues: do not copy to build queue
+ --no-new-packages: do not copy new packages
+ -> source-based, new binaries from existing sources will be added
+ --only-new-packages: do not update existing packages
+ -> source-based, do not copy new binaries w/o source!
+ --also-policy-queue: also copy pending packages from policy queue
+ --update-overrides: update overrides as well (if different overrides are used)
+ --no-act
