I don't really understand how this works. If on checkout $version $ is expanded, what gets commited back? $version $ or the actual number?

@version $Id: $

i.e. no expansion

To expand svn keywords in source files (especially the "@version $Id:
$" part). Why do we need this?

To be honest I'm not sure. I've always done and never questioned it
so I guess now is the right time to do so... :)

Pros I can think of:
- it allows us to distribute sources and if someone modifies it we
can know what version of the source they're using

Cons I can think of:
- more work, developers need to have keyword expansion set in their
subversion config file (although we would need subversion config
anyway for eol, mimetypes, etc)
- for developers, duplicates the information in SVN. It's mostly
possibly interesting for users and even then it's not sure

Note: in Svn the files are stored in the repo without the expansion;
it's only on checkout that the expansion happens.

Thus after more thought, I'm more tempted to say we don't need them
and that we should remove all the @version I've added here and then
(I'll do it of course should we agree to not use keyword expansion).

Thanks
