Okay, I'm done reorganizing trunks, tags, and branches in SVN.
Here's how things have changed around:
https://svn.sourceforge.net/svnroot/inkscape/trunk/$module -> https://svn.sourceforge.net/svnroot/inkscape/$module/trunk
https://svn.sourceforge.net/svnroot/inkscape/branches/$branch/$module ->
https://svn.sourceforge.net/svnroot/inkscape/$module/branches/$branch
https://svn.sourceforge.net/svnroot/inkscape/tags/$tag/$module -> https://svn.sourceforge.net/svnroot/inkscape/$module/tags/$tag
For example, to check out inkscape's "HEAD" used to be:
https://svn.sourceforge.net/svnroot/inkscape/trunk/inkscape
Now it's:
https://svn.sourceforge.net/svnroot/inkscape/inkscape/trunk
Note that you will need to explicitly specify the checkout directory name if you don't want it to be "trunk" (you probably don't). That means that, in order to check out into an "inkscape" directory, you now do:
svn checkout https://svn.sourceforge.net/svnroot/inkscape/inkscape/trunk inkscape
Any questions?
