While talking of unixy ways to delete the folders, wouldn't it be better
to simply move them aside for a while. Otherwise you'd have to do work
similar to a checkout to get the directory back under version control
again.

Say you directory is called "proj", I'll store the .svn directories in
proj.svn. I talk unix better than dos, but what I have in mind
is a little script like this:

    #!/bin/sh
    #
    # Move all .svn directories in $1 to $2.
    # $2 is created if it does not exist.
    #
    # TODO: handle character sed could choke on: [, \ and possibly others.
    # TODO: handle moves from . to ../dir

    if [ $# -ne 2 ]; then
        echo "$0: please specify two paths." >&2
        exit 1
    fi

    from="$1"
    to="$2"

    # sed does: quote the path, save it, replace $from by $to, strip
    # .svn from $to, append $to to the saved $from, create the
    # command to run (two steps), replace newlines from H and G
    find "$from" -type d -name .svn \
        | sed -e 's:.*:"&":' \
              -e h \
              -e "s:^$from:$to:" \
              -e 's:.svn"$:":' \
              -e H \
              -e 's:.*:mkdir -p &; mv:' \
              -e G \
              -e 's:\n: :g' \
        | sh -x
    # EOS

Name the script eg. mvsvn and you could do

    $ mvsvn project project.svndirs

use the clean version of your project, and then revert your changes with

    $ mvsvn project.svndirs project
