module Pod

# @note The backing store of the podspecs collection is an implementation detail
# abstraced from the rest of CocoaPods.
#
# @note The default implementation uses a git repo as a backing store, where the
# podspecs are namespaces as:
#
# #{POD_NAME}/#{VERSION}/#{POD_NAME}.podspec
#
# @todo For better abstranction the sources should be responsible to update themselves.
