subversion managed store.
|
|
|
|
The shove psuedo-URL used for a subversion store that is password protected is:
|
|
|
|
svn:<username><password>:<path>?url=<url>
|
|
|
|
or for non-password protected repositories:
|
|
|
|
svn://<path>?url=<url>
|
|
|
|
<path> is the local repository copy
|
|
<url> is the URL of the subversion repository
