Scenario: subversion repository installed on a home-server. Sometimes you need to interact with it from the L.A.N. and sometimes from internet.
This script other then being a wrapper for svn, checks whether the working copy needs to be relocated or not before the operations.

GATEWAY_IP=192.168.0.254
GATEWAY_MAC=00:14:6c:ab:d2:ca

REPO_REMOTE=code.matteolandi.net
arp -a | grep $GATEWAY_MAC > /dev/null
if [ $? -eq 0 ]; then
source=$REPO_REMOTE
destination=$REPO_LOCAL

url_before=$(svn info | grep URL | cut -d ' ' -f 2)
url_after=${url_before/$source/$destination}
if [ "$url_before" != "$url_after" ]; then
echo "Relocating ${url_before} -> ${url_after}"
svn switch --relocate $url_before $url_after
if [ $? -ne 0 ]; then
exit 1

I know you could create a new entry inside /etc/hosts and use it depending on the situation, but easy solutions are not my best!
Obviously you will find it inside the hacks/svn-tools repository.
