svnadmin deltify — Deltify changed paths in a revision range.
svnadmin deltify only exists in 1.0.x due to historical reasons. This command is deprecated and no longer needed.
It dates from a time when Subversion offered administrators greater control over compression strategies in the repository. This turned out to be a lot of complexity for very little gain, and this “feature” was deprecated.
