Changing the URL of a SharePoint Site Collection

Noticed that a site collection had a poor URL - to change the URL, backup the site and then restore using stsadm command-line operations:

To backUp:
stsadm -o backup -url {existing site collection URL} -filename {name of file}

To restore:
stsadm -o restore -url {new site collection url} -filename {name of file}

Thanks to Jose Barreto for saving me the task of rebuilding the collection from scratch
