%description
Because larger (> 50 MB) data files cannot easily be committed to git, a
different approach is required to manage data associated with an analysis
in a GitHub repository.  This package provides a simple work-around by
allowing larger (up to 2 GB) data files to piggyback on a repository as
assets attached to individual GitHub releases.  These files are not
handled by git in any way, but instead are uploaded, downloaded, or edited
directly by calls through the GitHub API. These data files can be
versioned manually by creating different releases.  This approach works
equally well with public or private repositories.  Data can be uploaded
and downloaded programmatically from scripts. No authentication is
required to download data from public repositories.
