What is meant by "subversion can handle binary files" is not referring
to the work process, but rather how the backend handles it.

AFAIK, In CVS, if you check in a binary file, edit it, then commit it,
that binary file will simply be re-uploaded to the CVS server, with no
diffing done. So if the file is 2MB, then you edit, save, and the file
is now 2.1MB, it will now take up 4.1MB in the repository.

With svn, that same file would now take up ~2.1MB in the repos after the
