* Subversion Switch command manager class
|

55 |
*
|
|
|
56 |
* Update the working copy to a different URL.
|
|
|
57 |
*
|
|
|
58 |
* From 'svn switch --help':
|
|
|
59 |
*
|
|
|
60 |
* usage: 1. switch URL [PATH]
|
|
|
61 |
* 2. switch --relocate FROM TO [PATH...]
|
|
|
62 |
*
|
|
|
63 |
* 1. Update the working copy to mirror a new URL within the repository.
|
|
|
64 |
* This behaviour is similar to 'svn update', and is the way to
|
|
|
65 |
* move a working copy to a branch or tag within the same repository.
|
|
|
66 |
*
|
|
|
67 |
* 2. Rewrite working copy URL metadata to reflect a syntactic change only.
|
|
|
68 |
* This is used when repository's root URL changes (such as a schema
|
|
|
69 |
* or hostname change) but your working copy still reflects the same
|
|
|
70 |
* directory within the same repository.
|
|
|

|
|
