SF makes nightly snapshots of whole CVS repository automatically (read
-> this fragment of docs ). You can download it (106 MiB :/ , download manager is a must) from
-> this link, unpack and then checkout current sources from local copy of repository. 106 MiB is rather big file, but it takes much less then 4 hours to download it (if You have good internet connection).
Not the best solution, but ... a solution.
EDIT: Argh... I thought You mean only PS sources... CS is too big, I\'m afraid, to download it this way.
