# Generates a component.v1 manifest.
#
# This template will cause a v1 component manifest to be generated.
#
# This template is typically not used directly. Instead, use templates like `fuzzer`.
#
# Parameters:
#   manifest (required)
#     [file] This is the filename of the manifest to be generated. It must end in ".cmx" or ".cml".
#
#   binary (required)
#     [string] Output name of the program binary invoked by this component manifest.
#
#   args (optional)
#     [list of strings] Additional program arguments to pass to the program binary.
#
#   features (optional)
#     [list of strings] Sandbox features requested by the component binary. Only valid if `manifest`
#       ends in ".cmx", i.e. if a component.v1 manifest is requested. See also
#       https://fuchsia.dev/fuchsia-src/concepts/components/v1/component_manifests#sandbox.
#
#   services (optional)
#     [list of strings] Sandbox services requested by the component binary. Only valid if `manifest`
#       ends in ".cmx", i.e. if a component.v1 manifest is requested. See also
#       https://fuchsia.dev/fuchsia-src/concepts/components/v1/component_manifests#sandbox.
#
#   metadata (optional)
#     [scope] Usual meaning.
