By creating a .repo/local_manifest.xml the user can add extra
projects into their client space, without touching the main
manifest script.
For example:
$ cat .repo/local_manifest.xml
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="android-build"
name="platform/build"
remote="korg"
revision="android-1.0" />
</manifest>
