Generates CDK CLI configurations from the source of truth in packages/aws-cdk/lib/config.ts. Currently generates yargs config into packages/aws-cdk/lib/parse-command-line-arguments.ts and strongly-typed CLI arguments interface into packages/aws-cdk-lib/cli-arguments.ts.

import { renderYargs } from '@aws-cdk/cli-args-gen';

declare const config: CliConfig;

fs.writeFileSync('./lib/parse-command-line-arguments.ts', await renderYargs(config));

This package exports renderYargs(), which accepts the CLI command config as input and returns the yargs definition for it as a string.

Some values must be computed at runtime, when a command is run. This is achieved with dynamic values; if the framework sees a CLI option with a dynamicValue, then the framework will reference the corresponding parameter. We should automatically generate the parameter definitions, instead of manually adding them, in the future.
