Note that on a large tree, having a revlib for _every_ revision is still
a bad idea -- all those directories really do start to add up, as do
duplicated parts of files (if a small patch is applied to a file, the
rest of the file is overhead).

However, they are very useful at greater intervals; I already use the
poor-man's version of revlibs, `cp -a', to keep every released linux
tree, and I'm sure many others too.

80% of success is just showing up.  --Woody Allen
