Executes the same shell command in each project.
Environment
-----------
pwd is the project's working directory. If the current client is
a mirror client, then pwd is the Git repository.
REPO_PROJECT is set to the unique name of the project.
REPO_PATH is the path relative the the root of the client.
REPO_REMOTE is the name of the remote system from the manifest.
REPO_LREV is the name of the revision from the manifest, translated
to a local tracking branch. If you need to pass the manifest
revision to a locally executed git command, use REPO_LREV.
REPO_RREV is the name of the revision from the manifest, exactly
as written in the manifest.
shell positional arguments ($1, $2, .., $#) are set to any arguments
following <command>.
stdin, stdout, stderr are inherited from the terminal and are
not redirected.
