# Writes an implementation of
# |org.chromium.components.module_installer.builder.ModuleDescriptor| for a
# particular module to Java. The module loader backend expects such an
# implementation for each module to automate module setup on first access.
# Instantiations of this template can be depended on like |android_library|
# targets.
#
# Supports the following variables:
# module_name: Name of the module.
# shared_libraries: (Optional) List of shared_library targets the module
# requires at runtime. Will consider all transitively depended on
# shared_libraries.
# paks: (Optional) PAK files going into the module.
# load_native_on_get_impl: (Optional) Whether the module's native libraries /
# resources are automatically loaded when Module.getImpl() is called.
