This is a Python downloader library with a Tkinter progress interface. A caller supplies a URL, destination, headers, and options; the public download workflow checks response size and range support, schedules concurrent byte-range retrieval, assembles temporary pieces into the destination, and reports per-worker progress and status. The range tracker reallocates unfinished spans, supporting recovery during a running download, while the interface derives speed and timing statistics. The excerpts omit some function bodies, so links for undocumented resume behavior and UI lifecycle details are limited to the documented capabilities and visible calls.
