+# Generates a static catalog manifest to be loaded at runtime. This manifest
+# contains the union of all individual service manifests specified by the
+# template parameters.
+#
+# The output of a catalog rule is always a file named:
+#
+#     ${target_gen_dir}/${target_name}.json
+#
+# A Service Manager embedder uses a catalog manifest as its singular source of
+# truth regarding available services in the system.
+#
+# Parameters:
+#
+#   embedded_services (optional)
+#       A list of names of services which must be embedded by the Service
+#       Manager embedder's binary in order to function. Services listed here
+#       should have a corresponding service_manifest rule entry in deps.
+#
+#   standalone_services (optional)
+#       A list of names of services which must be available to the Service
+#       Manager at runtime, in a Packages/ directory relative to the Service
+#       Manager embedder's binary.
+#
+#    executable_overrides (optional)
+#       A list of overrides to apply in catalog metadata for individual
+#       services. An override string must be of the form
+#
+#           "<service_name>:<executable_path>"
+#
+#       The special token @EXE_DIR may be used in |executable_path| to denote
+#       a path relative to the Service Manager embedder's binary, substituted
+#       at runtime. For example:
+#
+#           "content_browser:@EXE_DIR/chrome"
+#
+#       would indicate to the Service Manager embedder that the
+#       "content_browser" service can be started by running the "chrome"
+#       executable in the embedder's own directory.
+#
+#    included_catalogs (optional)
+#       A list of other catalog files to be included within this catalog.
