|
|
The '%prog' command synchronizes local project directories
|
|
with the remote repositories specified in the manifest. If a local
|
|
project does not yet exist, it will clone a new local directory from
|
|
the remote repository and set up tracking branches as specified in
|
|
the manifest. If the local project already exists, '%prog'
|
|
will update the remote branches and rebase any new local changes
|
|
on top of the new remote changes.
|
|
|
|
'%prog' will synchronize all projects listed at the command
|
|
line. Projects can be specified either by name, or by a relative
|
|
or absolute path to the project's local directory. If no projects
|
|
are specified, '%prog' will synchronize all projects listed in
|
|
the manifest.
