2.this drive or directory can be accessed either over internet or lan by plugging on to webdav
3.this helps in moving the integrated development environment and wiki and even test setup live over
web or local instantly

2.powerful with diff,patch,kompare
3.svk steps
create a symbolic directory structure of remote svn to local its called mirror
checkout a project from mirror to a local folder its called workcopy
do modification on workcopy
push to mirror
push from mirror
reference links
