All these — svnadmin, svnlook, and svn over file:// — access
a repository on-disk directly, without a mediating server.

In these cases, there _is_ in fact a certain amount of leeway — the 1.5
svn* tools can read repositories created by 1.6, for example — but in
general it's recommended to use just one version of svnadmin/svnlook/svn
on a repository. (For example, because that minimises the chance of
running into compatibility bugs.)

In general, we promise for on-disk structures — i.e., for the part of
the stack where neither svn:// nor http:// is involved — that 1.x.y can
read data created by 1.a.b if x ≥ a; which notably includes the case
that x=a and y<b. However, mixing versions, or downgrading, is not
recommended.
