Well, you can do this additionally in another top-level directory
(without copying files around). With svn:external, you can declare a
pointer, a faked "directory" (like a symlink, that points to an online
resource). In reality, this is simply a SVN resource.

Consider, you create the following infrastructure:

categories/algebra
categories/graph
categories/pde

Now say package foobar in /packages/ would fit category algebra and
graph. So set:

svn propset svn:externals \
   "foobar svn+ssh://svn.debian.org/svn/pkg-scicomp/package/foobar" \
    categories/algebra

svn propset svn:externals \
   "foobar svn+ssh://svn.debian.org/svn/pkg-scicomp/package/foobar" \
    categories/pde

This will "create" the pointers

categories/algebra/foobar
categories/pde/foobar

If you check them out and take a look at .svn/entries you will see, that
the checkout path is still svn
+ssh://svn.debian.org/svn/pkg-scicomp/package/foobar, not something like
svn+ssh://.../categories/algebra/foobar.

Because these are just pointers, every update to the original location
of foobar will automatically appear in a checkout of categories. Ditto
for the opposite.

So this could be useful for people just interested in a special category
of software.
