Re: Subversion vs. VSS

One advantage (only one I can see) is that VSS manages binary files well,
i.e. it has exclusive locking. For this reason I would choose it over CVS
or subversion at this point, though SVN will have it after 1.0.

CVS has advisory locks, but might not be what you want (I know I don't)
for a large organization.

If you have binary data, be sure that your source control can manage it.
Exclusive locking is nessesary to prevent two people updating the same
file at the same time - which then requires they hand merge changes. This
is really really hard for some data formats (3d models with animation,
texture mapping, etc.. for example).
