Indeed, that's the correct principal. Here's my script:

#! /bin/bash

DRYRUN=""
if [ "$1" = "-n" ]; then
  DRYRUN="yes"
  shift
  echo "DRYRUN MODE"
fi

IFS='
'
for i in `${SVN-svn} status --no-ignore "$@" | sed -n 's/^[I\?] //p'`
do
  if [ "${i/,//}" != "$i" -o "${i/%.swp//}" != "$i" ] ; then
    echo "SKIPPING: $i"
  else
    echo "$i"
    if [ -z "$DRYRUN" ]; then
      rm -rf "$i"
    fi
  fi
done

I've made a few enhancements above the core functionality.

1. Dryrun (-n) mode

2. Handles whitespace in names (but not newlines)

3. Condenses the grep&cut into a single sed.

4. Skips *.swp files (vim swap).

5. Skips things with commas in the name. I use this to maintain unversioned
stores of scripts, notes, etc. within a working copy, and avoid accidentally
purging them.

I guess I should add this to tools/client-side/...

Max.
