Now we have reached the successful migration of the last writes to the old SVN repository.
The new SF SVN repo now contains the latest commits (around April 22nd, commit 5338).
I could send two commits in (SFEopus.spec), so you'll see repo revision 5340 now.

Your action:
****Important to get access to the new repository***
Start relocating your local copy of the
repository to the new URL.

You might want to do a backup of your local files first,
e.g. with:

svn diff > ~/my_copy_of_spec-files-extra-`date +'%Y%m%d-%H%M%S'`.svn_diff

and

gtar zcf ~/my_tarball_of_spec-files-extra-`date +'%Y%m%d-%H%M%S'`.tar.gz

then switch to the new repository URL with:

svn switch --relocate \
https://pkgbuild.svn.sourceforge.net/svnroot/pkgbuild/spec-files-extra/t... \
https://svn.code.sf.net/p/pkgbuild/code/spec-files-extra/trunk

After that, you should be able to do get updates to the repo:

svn up

(use svn info to see the revision, should be >= 5340)
