%description
    Git LFS is a command line extension and specification for managing
    large files with Git. By design, every Git repository contains every
    version of every file. But for some types of projects, this is not
    reasonable or even practical. Multiple revisions of a large file
    take up space quickly, slowing down repository operations and making
    fetches unwieldy. Git LFS overcomes this limitation by storing the
    metadata for large files in Git and syncing the file contents to a
    configurable Git LFS server.
