| # 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. |
