#     This script will check for the latest commit badge              #
#     and will return a version numeber that corresponds              #
#     to the semver spec.                                             #
#     Latest commit tag should have '(patch)', '(minor)' or '(major)  #
#     in the comment. The script is not case sensitive.               #
#     Other badges will be interpreted as patch version               #
#                                                                     #
