The latest repo source code and manifest collection is downloaded from the server and is installed in the .repo/ directory in the current working directory. The optional -b argument can be used to select the manifest branch to checkout and use. If no branch is specified, master is assumed. The optional -m argument can be used to specify an alternate manifest to be used. If no manifest is specified, the manifest default.xml will be used. The --reference option can be used to point to a directory that has the content of a --mirror sync. This will make the working directory use as much data as possible from the local reference directory when fetching from the server. This will make the sync go a lot faster by reducing data traffic on the network. Switching Manifest Branches --------------------------- To switch to another manifest branch, `repo init -b otherbranch` may be used in an existing client. However, as this only updates the manifest, a subsequent `repo sync` (or `repo sync -d`) is necessary to update the working directory files.
