Hi, many thanks for writing this excellent tool.

Just thought you might want to consider, your README.md mentions:

# Download the script and save it to /usr/local/bin wget -O /usr/local/bin/semver \ https://raw.githubusercontent.com/fsaintjacques/semver-tool/master/src/semver

But the source file doesn't include attribution or license terms, which are required by the Apache v2.0 terms you selected. This immediately leads your users into violating the terms of your license. May want to include a comment header w/ copyright, terms, etc. or change the license to one that doesn't require attribution.
