5 Usage: $0 [-h] [-a] [-r] [-k] [-w] [-b Commit/Tag/Branch]
6
7 -a Apply all the changes to all repositories in the current tree.
8
9 -b Update to a commit/tag/branch. This is useful if you work on a single
10 branch/tag in all repositories. If the requested repository is not
11 found it falls back to the recent version. The -k and -i options are
12 useful here.
13
14 -h Prints this usage information
15
16 -i Update to a commit/tag/branch with the -b flag in interactive mode.
17 This asks if you want to fall back to the recent version if the
18 requested commit/tag/branch is not found.
19 This is only useful with the -b flag.
20
21 -k This does not pull from the remote repository, just updates the
22 repositories.
23
24 -r Revert to the last version. This is not deleting the pull commit,
25 just updating back to your last state.
26
27 -w Do the pull over https instead of ssh
