Currently I do not often use Subversion as a coder but I keep up with the source trees of some projects managed with it.
Since I do not have permanent internet access I like to have a change log for every such project available on disk.
Also, on updates, I would like to see what's new and have the changes merged into the change log.
The latter is achieved with the short svn2cl-accum perl script which emulates the behaviour of the cvs2cl --accum for CVS repositories.
