# frozen_string_literal: true
# Class to parse manifest file and build a list of repositories for import
#
# <manifest>
# <remote review="https://android-review.googlesource.com/" />
# <project path="platform-common" name="platform" />
# <project path="platform/art" name="platform/art" />
# <project path="platform/device" name="platform/device" />
# </manifest>
#
# 1. Project path must be uniq and can't be part of other project path.
# For example, you can't have projects with 'foo' and 'foo/bar' paths.
# 2. Remote must be present with review attribute so GitLab knows
# where to fetch source code
