18 | 18 | This finds all changes from the repository at the specified path |
|
19 | 19 | or URL and adds them to the local repository. |
|
20 | 20 | |
|
21 | 21 | If the pulled changes add a new branch head, the head is |
|
22 | 22 | automatically merged, and the result of the merge is committed. |
|
23 | 23 | Otherwise, the working directory is updated to include the new |
|
24 | 24 | changes. |
|
25 | 25 | |
|
26 | 26 | When a merge is needed, the working directory is first updated to |
|
27 | 27 | the newly pulled changes. Local changes are then merged into the |
|
28 | 28 | pulled changes. To switch the merge order, use --switch-parent. |
