Jiri manifests are revisioned and stored in a "manifest" repository, that is
available locally in $JIRI_ROOT/.manifest. The manifest uses the following XML
schema:

 <manifest>
   <imports>
     <import name="default"/>
     ...
   </imports>
   <projects>
     <project name="release.go.jiri"
              path="release/go/src/v.io/jiri"
              protocol="git"
              name="https://vanadium.googlesource.com/release.go.jiri"
              revision="HEAD"/>
     ...
   </projects>
   <tools>
     <tool name="jiri" package="v.io/jiri"/>
     ...
   </tools>
 </manifest>

The <import> element can be used to share settings across multiple
manifests. Import names are interpreted relative to the $JIRI_ROOT/.manifest/v2
directory. Import cycles are not allowed and if a project or a tool is specified
multiple times, the last specification takes effect. In particular, the elements
<project name="foo" exclude="true"/> and <tool name="bar" exclude="true"/> can
be used to exclude previously included projects and tools.

The tool identifies which manifest to use using the following algorithm. If the
$JIRI_ROOT/.local_manifest file exists, then it is used. Otherwise, the
$JIRI_ROOT/.manifest/v2/<manifest>.xml file is used, where <manifest> is the
value of the -manifest command-line flag, which defaults to "default".
