With the -o option, exports the current manifest for inspection.
The manifest and (if present) local_manifests/ are combined
together to produce a single manifest file. This file can be stored
in a Git repository for use during future 'repo init' invocations.
The -r option can be used to generate a manifest file with project
revisions set to the current commit hash. These are known as
"revision locked manifests", as they don't follow a particular branch.
In this case, the 'upstream' attribute is set to the ref we were on
when the manifest was generated. The 'dest-branch' attribute is set
to indicate the remote ref to push changes to via 'repo upload'.
