| """Satip Download Manager | ||
| This module provides a unified interface for downloading EUMETSAT and GOES | ||
| satellite data via the `DownloadManager` class. Users specify the provider | ||
| ('EUMETSAT' or 'GOES'), and the manager delegates tasks to dedicated | ||
| sub-modules for retrieval, storage, and logging. | ||
| Key functionalities: | ||
| * Download data for a specified time range. | ||
| * Handle user authentication (for EUMETSAT data). | ||
| * Manage data retrieval, storage, and logging for both providers. | ||
