It seems that since a pickle might happen to contain spurious
instances of the string "$Id:" (or one of the other things that CVS
replaces), you would want to turn off CVS's keyword replacement for
these files anyway.  (*Especially* if you're writing binary pickles.)

But if you're not going to do that, you could just adopt a convention
where the first line of the file is a comment.  To write one, you open
a file, write the command, and then dump the pickle data.  To read it
back, open the file, read and discard one line, then do a pickle load
on the rest of the file.
