# Basic script to update a git repository without any history or excess data in .git.
# Parses the url from .git/config, downloads latest version, and purges everything in .git/ except the config file.
# Limitations:
#   * Only works with the master branch.
#   * Doesn't account for local virtual environments.
#   * Doesn't allow for maintaining a stash of changes.

    # remove all files from the current directory
    rm -rf ..?* .[!.]* *
    # clone the parsed url into the currect directory

    # clean up the .git directory
