# Used to produce a Mojo Application Manifest for an application.
#
# Parameters:
#
# source
# The manifest file template for this application, must be valid JSON with
# a valid 'url' key matching application_name.
#
# base_manifest (optional)
# A manifest file template to use as a base for |source|. Any properties
# defined in |source| will overwrite or be merged with properties defined
# in |base_manifest|.
#
# application_name
# The host portion of the mojo: URL of the application. The script
# validates that the value of this parameter matches the host name portion
# of the 'url' property set in the manifest and throws a ValueError if
# they do not.
#
# base_deps (optional)
# Dependencies required to generate |base_manifest| if applicable.
#
# deps (optional)
# An array of dependent instances of this template. This template enforces
# that dependencies can only be instances of this template.
#
# packaged_applications (optional)
# An array of application_names of the dependent applications.
#
# type (default is mojo)
# Possible values are 'mojo' and 'exe'. Default is 'mojo'.
#
# Outputs:
#
# An instantiation of this template produces in
# $outdir/<application_name>/manifest.json
# a meta manifest from the source template and the output manifest of all
# dependent children.
