/**
 * The main entry point for interacting with the Aptos APIs,
 * providing access to various functionalities organized into
 * distinct namespaces.
 *
 * Note: Importing `Aptos` pulls in all sub-modules and is not tree-shakeable.
 * For smaller bundles, import namespace classes from sub-paths instead:
 *
 * ```typescript
 * import { General, AptosConfig } from "@aptos-labs/ts-sdk/general";
 * const general = new General(new AptosConfig({ network: Network.TESTNET }));
 * await general.getLedgerInfo();
 * ```
 *
 * Or for maximum tree-shaking, import individual functions:
 *
 * ```typescript
 * import { getLedgerInfo } from "@aptos-labs/ts-sdk/general";
 * await getLedgerInfo({ aptosConfig: config });
 * ```
 *
 * @example
 * ```typescript
 * import { Aptos, AptosConfig, Network } from "@aptos-labs/ts-sdk";
 *
 * const config = new AptosConfig({ network: Network.TESTNET });
 * const aptos = new Aptos(config);
 * const ledgerInfo = await aptos.getLedgerInfo();
 * ```
