Pegged Versions and get_file/cat

-----BEGIN PGP SIGNED MESSAGE-----

What exactly are pegged versions and how would you use then when calling
get_file or cat to get a files contents?

I'm still having a problem understanding the best way to get the
contents of a file whose dirent revision isn't the revision under which
the file can be found (like in a tags or branches directory copy).

For example:

        /repos/project/trunk/foo.txt Revision 22
        /repos/project/tags/0.01 Revision 23
        /repos/project/tags/0.01/foo.txt Revision 22

What's the proper procedure for getting the contents of
/repos/project/tags/0.01/foo.txt?

get_file('/repos/project/tags/0.01/foo.txt', -1) will get me the latest
revision, but that may not be the right one.

get_file('/repos/project/tags/0.01/foo.txt', 22) will yield a 404 not
found error because the file is really located at
/repos/!svn/bc/23/project/tags/0.01/foo.txt

get_file('/repos/project/tags/0.01/foo.txt', 23) will get me the version
that I'm interested in. But, how would I know how to get use 23 instead
of 22?

So, without any prior knowledge of whether a revision of a file is the
original, or a copy, what's the proper procedure here?

Should I always call getprops on /repos/project/tags/0.01/foo.txt which
will give me the real path of
/repos/!svn/bc/23/project/tags/0.01/foo.txt, and then use THAT path in
get_File?
