devel/py-pooch - The NetBSD Packages Collection

Does your Python package include sample datasets? Are you shipping
them with the code? Are they getting too big?

Pooch is here to help! It will manage a data registry by downloading
your data files from a server only when needed and storing them
locally in a data cache (a folder on your computer).

Here are Pooch's main features:

* Pure Python and minimal dependencies.
* Download a file only if necessary (it's not in the data cache
  or needs to be updated).
* Verify download integrity through SHA256 hashes (also used to
  check if a file needs to be updated).
* Designed to be extended: plug in custom download (FTP, scp,
  etc) and post-processing (unzip, decompress, rename) functions.
* Includes utilities to unzip/decompress the data upon download
  to save loading time.
* Can handle basic HTTP authentication (for servers that require
  a login) and printing download progress bars.
* Easily set up an environment variable to overwrite the data
  cache location.
