What? I previously had my private HOME directory versioned by CVS, at 
the beginning of the year I have moved to SVN for that. (I don't use the 
Berkeley DB format, but created via "svnadmin create --fs-type fsfs ...".

The CVS repository was about twice the size of my HOME, for SVN it is 
LESS THAN HOME!!! SVN zips the patches that are send to the repository.

I can understand the other goodies, but not the space considerations. 
SVK actually has the WHOLE original remote SVN repository stored locally 
as a "depot" under ~/.svk so that you can do things off-line. SVN just 
extracts a working copy (actually two since the files that you have 
checked out are in their original version additionally stored under the 
.svn directories.

I don't really know whether SVN or SVK needs more space.

I don't really understand. Creating a branch is done via "svn copy". If 
you look at the size of the REPOSITORY, you'll see that it has grown 
less then 1000 Bytes. SVN is just storing that the new branch is copied 
from the some origin. The actual copying takes place at checkout time.

But anyway... 100MB at google seems a bit to less for Axiom. ;-)
